Jack is both a victim and perpetrator of domestic violence. Jack’s father was an abusive alcoholic who beat and berated him. When Jack drank he used to parrot his father’s words (“take your medicine” “you damn pup”). He is primarily verbally abusive. The last incident of drinking that pushed him to sober up was accidentally breaking Danny’s arm. Wendy, perhaps like Jack’s mother, lied for him but swore she would leave if he didn’t sober up.
