Adam is a character introduced in season 2A as Connor's father. He is shown to be tough and hard on his son, causing them to have a strained relationship.
In later episodes, Adam seems a little more accepting of Jude and Connor's relationship since he allows Jude to spend time with Connor at his house. However, after he walks in on Jude and Connor making out and is not pleased, Connor considers moving in with his mother instead with Jude's support.
