Mr. Swemco is the father of Ayden Grit. He is cocky and uncaring of his children, a fact he makes clear causing him and his wife to divorce. However, his pride would not let her win the settlement and he got custody of Ayden while she got Ace. He refused to allow Ayden to move in with Ace prior to the events of Two Birds One Stone, causing her to run away. He reappeared in Fathers when Ayden went to pick up things she left at his apartment.
