Blackwall is a romance option and a party member, so he has four possible character cards. Unlike some of the other party members, his personal quest is sort of mandatory – when you reach a certain stage of the game it will be triggered, and he’ll leave your party either temporarily or for good if you choose not to chase after him. While he’s away you’ll see the dark, sad character card. If you choose to bring him back and restore his faith in himself, you’ll get the bright, triumphant card. Finally, if you romance Blackwall you’ll see card representative of his devotion.
