Scorsone further explained that the drama between Alex and Jo will play a huge role throughout the season. When last we left the couple, Jo had turned down Alex's proposal because she's still secretly married to her abusive ex-husband (which Alex doesn't know about), and later, Alex finds her in a compromising position with DeLuca that wasn't what it looked like (but he beats the guy to a pulp anyway). "It's very explosive, very exciting and interesting on social levels and personal character levels," said Scorsone.
