Notably: he's not caring who he damages at first. Then John will "point him in the right direction" so to speak and he will purposefully help the Barge side of things. And he's witnessing Aerith's fall and is Not Happy about it and going a little berserk.
I'm tired tonight but hopefully this week I can figure out whether I'm hitting up individual inboxes or making a post, but either way Collins is going to ask people if they're all right and actually kind of but not really admit he cares. just a little bit.
If he does admit to any feelings, it might mean his graduation. This was what the event meant the most to me so I am glad for the opportunity for him to care a bit.
