Hm. Maybe after everything, he felt like he didn't deserve to be saved.

[ Or he could just be a dick with too much pride. Gladio hasn't met him, so it's tough to judge the man, but he's trying to give Lightning the most hopeful answer. The kind that shouldn't make her feel bad for even trying. Can he believe that she tried to save someone like that? Honestly, no, but... it warms his heart to know she's capable of such forgiveness. She did the right thing, even if she failed.

Still, the mystery here is why she failed, and it may not be her fault at all. ]

Reckon he's the kinda type with capacity for self-reflection?
