Jesse experienced Darcey's "out of control" responses to him when she came back from drinking with his mother. Jesse is ALL about control. He called her the B word to shame her into submission. He uses aggression to immediately gain control of the situation. Anyone ever wonder why he hasn't found a local girl? No one would tolerate that kind of intensity more than in small doses.
Controlling behavior often escalates. It would not be surprising for physical assaults to the be the next step.
