What can we expect for Castle and Beckett's relationship as we head to the end of Castle's season? — Dana
ADAM: The bumps that we've hinted at before will be exacerbated by two men who come into Beckett's life. First, Beckett will be assigned to protect multimillionaire inventor Erik Vaughn (Ioan Gruffudd) — in his private hotel penthouse. "If Castle aspired to be someone, he'd aspire to be this guy," creator Andrew W. Marlowe says. "Castle's really determined to solve the case and get his girlfriend away from him." During their alone time, Erik will ask Beckett some tough questions about where her relationship with Castle is headed. Unfortunately, as  Beckett wrestles with those questions in the season's penultimate episode, she'll cross paths with a federal investigator (Carlos Bernard) who might offer some different answers. "He opens Beckett's eyes on other possibilities that might be out there for her," Marlowe teases.
