After the “!!!!” moments of last week’s episode “Practically Perfect,” it makes sense that in feels like both DEXTER the series and Dexter the character (Michael C. Hall) are taking a little time to recover from various shocks and plan ahead. A good portion of “Beauty and the Beast” is concerned with Dexter’s dilemma over Lumen (Julia Stiles), the young woman who was captured and tortured by Dexter’s latest target. Problematically for Dexter, Lumen witnessed him killing Lumen’s captor. Dexter tries to nurse Lumen back to health – she’s got criss-crossing cuts all over her back – while trying to figure out what he can do that won’t cause either of them to die. Harry’s shade (James Remar) urges Dexter to kill Lumen, as the number one rule remains “Don’t get caught,” but Harry instead tries to get the wary woman to trust him. When she does, it turns out that Dexter’s victim wasn’t her only tormentor, and now that Lumen knows she’s not going to be killed, she wants payback.
