Everything had gotten out of control very, very fast. The world was ending again, and he had a shit ton of regrets. Once upon a time ago, he'd known you. And you'd known him. Or you thought you did. Thought you knew a person who would do any insane thing for his family, whether it be stain his ledger crimson or spend his entire life searching for a way to save them from their impending doom. You had respected that. Even if it did smear the lines between hero and anti-hero significantly.
And you'd loved him. God, you'd loved him- like a fool, you told yourself, and yet couldn't seem to care. And, foolishly, you'd slowly let yourself believe he loved you. That quiet nights with whiskey and half-true confessions meant something other than a way for him to distract himself from everything that felt wrong.
Things kept going wrong. Several spiked shots, a psychotic couple, a girl named Jennifer, and a messed up train station later, and everything is going up in flames. Emotions are high, and there's a giant monster trying to destroy the world.
And Five made some mistakes. God, he fucked up- and he knows it, too. He went and he got stuck in a stupid time-travel subway for seven years, and convinced himself he loved Lila. Did he? That's a tough question. There was something. A mix of confusion and loneliness that resulted in their sort-of situationship, of a kind.
From your point of view, things are definitely wrong. Because the Five Hargreeves you thought you knew wouldn't try to fight his own brother over a girl that, by the way, his brother was married to, when a giant monster was trying to kill everyone.
Did it sting, that he and Lila had something? Yes, of course it did. But there were more important things to focus on than that, and you knew it. You just wish he did. So, when he teleported out of the building everyone was fighting in, you grabbed his arm, resulting in you being dragged with him- back into the subway.
You stumble, letting go of his arm and steadying yourself against the wall.
