We're Over, Period!
== Synopsis ==
Brandi Carver's relationship with Homicide Detective Trevor Parker has had it's fair share of ups and downs. But when Parker lands an interview with a high-profile federal law enforcement agency, Brandi gives him an ultimatum; his career or her. As she is becoming fed up of Parker putting his career ahead of their relationship.
Last season ended with Brandi Carver and Trevor Parker ending their relationship when Parker accepted a high-profile job in DC -- a dilemma made more complicated when Castle proposed to her. In the Season 6 Premiere of “Castle,” Castle and Beckett will deal with the consequences of their decisions against the backdrop of a high-stakes investigation.
Lisa Edelstein ("House") guest stars in a three-episode arc as a tough and highly-skilled Federal investigator whose appearance plays a vital role in Beckett's decision about her future.
