Forever (on abc) is a show about immortality. The main character doesn't physically age, and reappears (naked and in water) every time he dies.

Someone on Daredevil is immortal, following the rules of the show.

possibilities:
> Matt gets 'killed' one night and has to parkour his way across the city while naked.
> Karen's mysterious past??? Yep immortality. Shit's happened.
> Ben Ulrich, because I don't want him dead.
> Foggy was so mad at Matt about the heartbeat thing because he was concerned his secret was revealed (also how would he handle looking like a college student his whole life lmao)
> Wesley. Poor Karen gets the shock of her life. (Fisk knows but is still mad because a death still hurts even when it doesn't stick)
> anyone really.
