Castle

The first part of Castle's two-part event, Season 4, Episode 15, "Pandora," introduced us to yet another of Rick Castle's former flames — Sophia Turner, a CIA agent who inspired the lead female character in his Derrick Storm series.

As predicted, Kate Beckett gets another case of the Green-Eyed Monster, but according to actress Jennifer Beals who plays Sophia, KB has absolutely nothing to worry about.

"She's not trying to get [Castle] back," Jennifer dishes to TV Guide.

"One of the things I said to [creator Andrew W. Marlowe] is that I'm not interested in playing a scenario where two women are fighting over the same man. Sophia can introduce lots of complications and lots of tension, but I wasn't interested in a catfight."

Nonetheless, Sophia's presence in the two-parter will inevitably force Kate to question her feelings for Castle … and his feelings for her.

In our opinion, Beckett's grown a bit complacent knowing she's Rick's no. 1 girl. Seeing the tension-filled glances between Sophia and Castle could remind the detective that she's not the only fish in the sea … and that she'd better do something before he moves on to different waters!

"Beckett has to wrestle with where she thought she stood in Castle's life and where she might really stand in Castle's life," Andrew Marlowe says.

"I think it serves as a bit of a touchstone for them. It certainly brings up stuff in both of our characters about how they're handling the relationship and getting a sense of what they want, what they're afraid of, and what they hope might happen."
