Twenty years before the events of season 3, he was in the boys locker room changing when an older jock dropped his towel and approached him to invite him to a party. When doing so, Angel tried to not look at the guy's crotch. Unfortunately he wasn't successful and when others joined the locker room, the guy freaked out. This resulted in the jock turning on him and the other jocks began to attack him with wrapped towels and a belt, leaving marks on his back.
After being tricked into going to the basement where he met Dan Olenski, and their faces were stapled together. Once finally removing themselves from each other, Angel learned that the furnace was roasting the dead bodies of Joe Lickers and Violet Lickers. When Connor returned, he held him into the furnace, causing him to suffer fatal burn injuries on his arms. This resulted in his death.
When the Jalalzai moved in, he wore a pride t-shirt.
Angel was helpful toward people, likely due to wishing he had been given support when growing up gay. He tried to get donations for the Jalalzai family when they moved in, and offered a homeless man temporary labor at the community center. However, his patience had limits, as he became frustrated when Kit had sex with Cassidy (despite Kit telling him he wasn't for monogamy), disliked Violet Lickers and begged Joe to leave her, eventually rejecting him when he did not, and had contempt for Dan Olenski. He was also somewhat vengeful, though not violently so, as he drugged Kit to expose his lechery to Cassidy.
