History with Stilinski
Donovan's father was a cop and Sheriff Stilinski's partner before he became the sheriff. In a shootout, Donovan's father was paralyzed after getting shot in his spine.
Donovan was in a motorcycle accident while trying to get to the hospital to see his father. His injuries required surgery for internal bleeding. He needed a skin graph afterwards which would make him a genetic chimera. (Strange Frequencies)
He would hold a grudge against Stilinski for believing he hid and called for back up instead of helping his father. It only deepened when he applied to be a Sheriff's Deputy to be a cop like his father and was not allowed.
He frequently threatens to kill him. The Sheriff says he is aware of Donovan's issues due to the testing he underwent when applying to work there.
