It's no secret that nurse Sam Taggart's ex, the father of her son, is no good. Besides getting Sam pregnant at 15, the guy was a criminal who'd landed himself in jail. But his most deplorable actions began on the Season 12 finale, when, after being treated for wounds sustained from a prison fight, he and some fellow prisoners shot up the ER and took Sam and her son, Alex, hostage. Things took an even more gruesome turn on the 13th-season premiere. With Alex asleep in the car, Steve insisted he wanted his family back before raping a frightened Sam. Later, with Steve passed out on the ground, Sam managed to make it back to the car with the intention of escaping. But before she left, she decided to finally take her revenge. In a gripping scene, Sam grabbed her sleazy ex's gun and shot him dead at point-blank range before fleeing with her son and never looking back. ("Bloodline," 9/21/2006) less
