The first look at season 4 of Sullivan's Crossing hints at issues between Maggie and Cal after the arrival of her secret husband. In a trailer released on Friday, February 6, Maggie (Morgan Kohan) says she was "finally in a good place" with Cal (Chad Michael Murray) before Liam (Marcus Rosner) arrived to Sullivan's Crossing. Maggie asks why Liam is there, to which he replies, "Can't a husband pop in to check on his wife?" Cal, meanwhile, questions why he didn't know about Liam.
