Banagh is a Scavenger living in the Swallows. He is in a relationship with Ann Nah who he becomes worried about when she fails to contact or see him for a prolonged period of time. Since Scavengers are forbidden from leaving the Swallows he has to send someone else to check on her.
Ann Nah explains they’ve reached a rough spot in their relationship and depending on how the player handles the conversation she’ll either break up with Banagh or agree to see him one last time. When told she’ll see him again Banagh asks the player to accompany him as he has trouble expressing his feelings. Banagh and Ann Nah then patch up their relationship and permanently leave the Swallows and University respectively to be together.
