Season three will see Brandon Flynn's Justin Foley adjusting to life as part of Clay's family, as well as dealing with the repercussions of hooking up with Jessica. Justin may also be in trouble in season three, as the last season ended with a menacing shot of Seth (Justin's mom's abusive and drug dealing boyfriend) watching Clay and Justin talking in Monet's from his car. Now that the Jensens are going to adopt Justin, Seth may just cause trouble for the whole family — especially if Justin can't kick his heroin habit.
