This week's Castle episode could reveal a connection between a young woman's murder and the man behind the murder of Beckett's mother. The TV.com episode summary goes:

"Complications ensue when Castle and Beckett finally try to take Senator Bracken down after finding evidence connecting him to a young woman's murder."

In an interview with TVGuide.com, Coleman dishes his thoughts on Beckett's situation.

"She's very much on the horns of a moral dilemma. Every fiber of her being is crying out for vengeance. But [if she kills him], what does she become? What does that say about her? There are no easy answers here," he said.

Is there a connection between the murdered young woman and Beckett's mother, too? How will Beckett hold herself together this time in the presence of a very dangerous enemy? Viewers can expect Castle to be very watchful of Beckett. He knows her concept of justice is in a muddle when it comes to her mother.

"It puts Castle in a position where he's waiting and watching to see what she's going to do with deep concern," series creator Andrew Marlowe told TVGuide.
