A case for Kastle | A way forward (my fan theory)
In the comics, Karen Page’s brutal death at the hands of Bullseye shattered Matt Murdock. But the MCU has a rare opportunity to subvert that fate: what if Karen doesn’t die… but fakes her death?
Instead of a corpse, she leaves behind a carefully orchestrated lie. A final, irreversible act to protect herself and the people she loves. A way to take control of a life that has been defined, over and over again, by other people’s violence.
Karen has been teetering on the edge of darkness since Daredevil Season 1, when she shot James Wesley. As more of her past is revealed—marked by guilt, grief, and survival—we see a woman constantly forced into life-or-death decisions. That history, and her relentless pursuit of truth and justice also makes her a permanent target for Wilson Fisk. To remain Karen Page is to remain vulnerable. And after Born Again opened with the devastating loss of Foggy Nelson, to kill off Karen too would feel like another lazy gut-punch. Just more pain to fuel Matt’s torment.
But a faked death? That’s not trauma for shock value. That’s character evolution. A conscious choice that preserves Karen’s autonomy, lets her reclaim the narrative and grants her a rare gift in genre storytelling: the chance to walk away from trauma on her own terms.
Karen’s reinvention
After losing Foggy and distancing herself from Matt, Karen relocates to San Francisco, trying to rebuild a life out of the wreckage. But we know, she can’t stay away.
We’ve watched her grow: from a small-town girl with a tragic past, to a murder suspect, to Nelson & Murdock’s moral anchor, to a fearless investigative journalist at the Bulletin. Karen has reinvented herself before. But this would be her boldest reinvention yet. A total reclamation. Killing “Karen Page” allows the woman underneath to finally live.
MCU continuity
The MCU has already built the scaffolding for a story like this. Faked deaths. S.H.I.E.L.D. coverups. Clean slates. If Frank Castle can be given a second life, why not Karen? This opens the door for powerful storytelling while honouring the existing gritty, grounded, and emotionally complex tone of Daredevil and The Punisher.
It also offers other character threads to be woven: Dinah Madani, David Leiberman, and more. A storyline where Karen fakes her death could organically pull some of those characters back in for final, meaningful resolutions without stretching plausibility.
Matt’s path forward
Karen’s "death" would devastate Matt, but it would also liberate him. It carries the emotional weight of her comic death, but with a quieter, more tragic finality. She’s not taken from him. She chooses to go. And in many ways, that choice might be even harder to bear.
But narratively, Daredevil is designed to endure. In the comics, he has loved and lost many times, and within the current state of the MCU has several romantic avenues to explore (Elektra, Kirsten McDuffie, She-Hulk, the list goes on). His romantic arc can evolve without being forced to erase or overwrite what he had with Karen.
And let’s be honest—the MCU rarely lets its heroes keep their great loves. From Star-Lord to Doctor Strange to Peter Parker, romance is often sacrificed on the altar of serialized storytelling. If Daredevil is here to stay (which it appears he is), a respectful, mature close to Matt and Karen’s chapter, one where she gets to decide when it ends, feels like the right choice.
How this ties into the Kastle ship
Frank Castle is nearing the end of his war. His body is breaking down—Born Again hints at his dependence on painkillers. His mission is losing meaning—everyone involved in the murder of his family is already dead. His grief has calcified into something quieter, heavier, more remorseful. “Look what it got me,” he tells Matt. One thread remains unresolved: his feelings for Karen.
Bullseye’s return forces a reckoning. And this time, Frank isn’t choosing between revenge and survival. He’s choosing between vengeance… and love.
In Born Again, Frank only springs into action when Karen calls on him—an unmistakable sign of his feelings for her. After their subtextually loaded moment together, their connection is further confirmed in a quiet conversation between Matt and Karen. Later, Frank is shown listening to radio chatter, monitoring the Punisher copycats. But he’s not tracking them for sport or ego. He’s listening for mentions of her. And when he hears them mention “the blonde”, and “hunting”, he moves. Because this isn't about his legacy. He couldn’t care less about that. What he cares about is protecting Karen.
If Karen were to fake her death, it would become a natural out for Frank as well. He could finally walk away from the Punisher—not in defeat, but in purpose. He becomes her shadow. Her shield. Because let’s be honest: Karen Page, even under a new name in a new place, will still be chasing truth. Still investigating. Still lighting fires. And when things get too close, she’ll need someone who can keep her safe. Frank can give her that. And she’ll give him what he needs, too. Connection. Stability. Family.
It’s the most fitting conclusion to the slowest burn in MCU history. Not explosive. Not dramatic. Just a quiet, earned escape.
Why Kastle works
The Kastle dynamic fits perfectly because it’s not about saving each other. It’s about understanding each other. Reflecting each other. Becoming something whole, together.
Frank facing mortality: Karen represents his last chance at something more than violence.
Karen choosing agency: Faking her death isn’t surrender, it’s a declaration of autonomy.
A poetic reversal: Frank lost his family to violence. Karen refuses to be lost in the same way.
And unlike Matt, whose romantic arc resets and reboots, Frank’s emotional world is singular. Monastic. If Karen is the only person who ever made him believe peace might be possible after the tragedy of his family’s murder, then her survival becomes the final thread anchoring him to life.
A fitting farewell
This twist respects the comics’ emotional beats but refuses to fridge Karen Page. Her “death” marks the end of a chapter, not a life. It allows Matt to grieve, Frank to grow, and Karen to finally, fully reclaim herself.
And most importantly, it understands a hard truth: in the MCU, happy endings are rarely loud. Sometimes, they’re quiet. Fragile. Earned. For Karen and Frank, that ending doesn’t lie in a grave. It’s somewhere else. Somewhere far, far away from Hell’s Kitchen.
A sunrise. A new name. A chance to be born again.

Okay hear me out;
What if they are gonna do a little cheeky swicheroo with Karen and Foggy? They already killed Foggy in the same way Karen dies in the comics right? And in those comics Foggy fakes his death and goes on to live his life with fake name etc. THAT would allow Karen and Frank to live happily ever after, somewhere far away, if Karen does it. They could even leave it so open ended it would satisfy all fanbases! Come on! JUST DO IT!
