Jack Brennan is dead, and the mystery surrounding his final hours is only getting more complicated. Now Chris McKenna, the actor who brought Brennan to life on General Hospital, has offered his own preferred suspect — and his choice could push one of Port Charles’ most troubled characters into even darker territory.
Chris McKenna Has His Own Pick for Brennan’s Killer
Chris McKenna has officially wrapped his run as Jack Brennan, but he does not appear to be finished thinking about the character’s death or the mystery it leaves behind.
In an exit interview following Brennan’s departure from General Hospital, McKenna admitted that the ending was not necessarily the one he would have chosen for the character. At the same time, he embraced the storytelling potential created by Brennan’s death, particularly if the show turns it into a long-running murder mystery capable of generating twists for months.
That possibility has already become one of the biggest talking points surrounding Port Charles. Brennan had accumulated enough secrets, enemies and leverage over other characters to make almost anyone connected to him look suspicious, which gives the writers plenty of room to keep viewers guessing.
McKenna, however, has one specific choice in mind.
He would like Willow Tait to be revealed as Brennan’s killer, joking that it may be time for Willow to take the next step and become capable of outright murder.
On the surface, the suggestion sounds provocative. Once Willow’s recent history is taken into account, however, the theory becomes much easier to understand.
Willow Had a Powerful Reason to Want Brennan Silent
Brennan knew something that could have caused enormous damage to Willow: he was aware of her involvement in the shooting and drugging of Drew Cain.
That knowledge gave him leverage.
If Brennan was prepared to expose Willow, turn evidence against her or use what he knew for his own purposes, she had a compelling reason to fear what he might do next. In a soap where secrets routinely become weapons, Brennan’s knowledge could have represented a direct threat to Willow’s freedom, relationships and future.
That makes McKenna’s theory more than a random wish from an exiting actor.
Willow has already been pushed into morally dangerous territory, and a revelation that she killed Brennan would mark a dramatic escalation rather than a completely disconnected turn. It would also force viewers to reconsider every recent scene involving her, particularly if she has been hiding far more panic and desperation than anyone realized.
The strongest version of that twist would not necessarily require Willow to have planned Brennan’s murder from the beginning. A confrontation could have escalated, Brennan could have threatened to expose her, or Willow could have acted impulsively in a moment when she believed she had no other way out.
Any of those possibilities would fit the kind of layered reveal General Hospital often uses in major murder mysteries.
Drew and Ava Are Already Too Close to Brennan’s Death for Comfort
Willow may be McKenna’s preferred suspect, but she is far from the only character with reason to worry about what happened to Brennan.
Drew Cain and Ava Jerome were already involved in events surrounding his final night. Drew persuaded Ava to keep Brennan occupied while he searched Brennan’s hotel room for information, and the use of drugged sleeping pills immediately places both of them inside a dangerous chain of events.
Even if neither one directly caused Brennan’s death, their actions make them vulnerable.
Once investigators begin reconstructing Brennan’s final hours, questions about who met him, what he consumed and who had access to his room could quickly expose details that Drew and Ava would rather keep hidden. Their involvement may therefore become less about whether they are guilty of murder and more about whether their cover-up makes them look guilty enough to become major suspects.
That distinction matters because murder mysteries in Port Charles rarely remain clean. Characters often begin lying to protect themselves from one crime or scandal, only to create behavior that makes them look responsible for something even worse.
Drew and Ava are already in exactly that position.
Nina’s Public Threat Gives the PCPD Another Obvious Suspect
Nina Reeves also enters the mystery with a major disadvantage: witnesses saw her in a heated confrontation with Brennan shortly before his death.
Carly Spencer witnessed enough of that exchange for investigators to take it seriously, and Nina’s anger gives the PCPD an easy motive to examine. Even if Nina never went near Brennan afterward, the simple fact that she openly threatened him before he died could become one of the first pieces detectives use when building their suspect list.
That makes Nina especially vulnerable if someone decides to push the evidence in her direction.
A public argument is not proof of murder, but it creates a narrative investigators understand immediately. If Brennan later turns up dead and Nina’s name is already associated with threats against him, every additional suspicious detail could reinforce the appearance of guilt.
That possibility becomes even more dangerous if Drew actively wants Nina blamed.
A murderer does not always need to create an entire case from nothing. Sometimes all it takes is finding the person who already looks suspicious and adding just enough evidence to make the story hold together.
Charlotte and Danny’s Discovery Could Become More Important Than It Seems
Charlotte Cassadine and Danny Morgan discovering Brennan’s body also raises questions that may not be fully answered yet.
Finding the victim does not automatically make either of them suspects, but their proximity to the scene means they could know something investigators have not yet realized is important. They may have noticed an object, heard something nearby or seen someone leaving the area before discovering Brennan.
In a mystery built around conflicting timelines, seemingly minor observations can become crucial later.
The fact that younger characters were the ones to make the discovery could also create complications for the adults trying to control the investigation. Charlotte and Danny may not initially understand the significance of everything they saw, which gives the writers room to reveal additional details only after detectives or family members begin asking the right questions.
A single overlooked detail could be enough to move suspicion from one character to another.
Brennan’s WSB Past Opens the Door to a Much Bigger Twist
The most obvious suspects all come from Brennan’s recent Port Charles storylines, but his history with the World Security Bureau gives General Hospital another option entirely.
Brennan did not arrive in town as an ordinary businessman. His work connected him to espionage, covert operations and enemies far beyond the people currently circling the Metro Court.
That means someone from his past could still emerge as the real killer.
An old adversary, former operative or person connected to a failed mission could have followed Brennan to Port Charles without anyone realizing it. If the show chooses that direction, nearly every current suspect could turn out to be a deliberate distraction.
Such a reveal would also make sense of Brennan’s complicated history because a man with that many dangerous connections would logically have threats extending well beyond Nina, Drew, Ava or Willow.
The drawback is that an outside suspect can feel less emotionally satisfying unless the writers connect that person directly to the characters already involved. For the strongest payoff, any surprise killer from Brennan’s past would need to explain not only why Brennan died, but also why the murder happened at this specific moment.
More Than One Person Could Be Responsible
There is another possibility that could make the mystery even more complicated: Brennan’s death may not have been caused by one person acting alone.
Several characters were already interfering in his life that night, and the circumstances surrounding his final hours leave room for multiple actions to have contributed to the outcome.
One person could have drugged him, another could have confronted him, and a third could have made the final decision that caused his death. That type of chain reaction would allow multiple characters to be guilty of different things without all of them being murderers.
It would also explain why so many people may feel the need to lie.
Ava could be hiding the pills. Drew could be hiding the break-in. Nina could be hiding a confrontation. Willow could be hiding an encounter no one knows about yet. Each secret would make its owner look worse while still leaving the true cause of Brennan’s death unresolved.
That is exactly the kind of structure that can sustain a long-running soap mystery.
McKenna’s Willow Theory Could Be a Clue — or a Perfect Misdirect
Chris McKenna naming Willow as his preferred killer does not mean the show has revealed the answer, but it does give fans a particularly interesting theory to examine.
Willow has motive. She has secrets Brennan could expose. She has already crossed lines that once would have seemed impossible for her character. Most importantly, making her the killer would create consequences far beyond a standard murder reveal.
It would affect Drew, Nina, Michael, Carly and several other families simultaneously.
That kind of fallout makes Willow an attractive candidate from a storytelling perspective because the reveal would not end with an arrest. It would detonate relationships across Port Charles.
At the same time, the fact that her motive is so compelling may be exactly why she is too obvious.
The writers could spend weeks making viewers believe Willow finally crossed the ultimate line, only to reveal that Brennan was killed by someone no one had considered seriously enough.
The Real Killer May Be Hiding Behind Everyone Else’s Secrets
What makes Brennan’s murder especially effective as a mystery is that almost every major suspect has something worth hiding even if they did not kill him.
That gives the investigation layers.
Drew cannot tell the whole truth without exposing his own actions. Ava has reasons to minimize her role in Brennan’s final night. Nina knows her public confrontation makes her look terrible. Willow has potentially devastating secrets Brennan could have used against her. Even characters who are innocent of murder may have enough guilt attached to other decisions to behave like suspects.
That allows General Hospital to keep shifting the audience’s attention without necessarily cheating the mystery.
Every confession can reveal a crime without revealing the murder.
Every piece of evidence can implicate someone without proving they caused Brennan’s death.
And every suspect can have a legitimate reason to panic even if the real killer is someone else entirely.
Who Really Killed Jack Brennan?
For now, Chris McKenna’s theory places Willow near the top of the conversation, but the case is far from settled.
Drew and Ava are already tangled in Brennan’s final hours. Nina has a public motive investigators can easily understand. Willow may have had the strongest reason to silence him permanently. Brennan’s WSB history leaves room for an enemy no one in Port Charles has even considered, and the possibility of multiple people contributing to his death cannot be ruled out.
That uncertainty is exactly what gives the storyline its potential.
The strongest murder mysteries are not built around one obvious suspect. They are built around several people who all look guilty for different reasons, forcing viewers to separate who is hiding something from who actually committed the crime.
Brennan’s death appears perfectly designed for that kind of story.
If McKenna gets his wish and Willow is eventually exposed as the killer, it would represent one of the darkest turns her character has ever taken. If he is wrong, his theory may still have pointed viewers toward the larger truth: Brennan knew too much about too many people, and someone finally decided that keeping him alive was more dangerous than getting rid of him.
Until General Hospital reveals who made that decision, every secret surrounding Brennan’s final night remains part of the case.
