We still don’t know if Kate Beckett (Stana Katic) will really head to D.C. for that high-profile FBI job this season, but regardless of where she is, her new mentor Rachel McCord (Lisa Edelstein) is a bit weary of her relationship with Castle (Nathan Fillion).

Lisa explains her character’s thoughts to TV Guide, revealing,"McCord views Castle as a threat to Beckett. He is hampering her potential."

Still, if there's one thing we know about Castle it’s that he’s as charming as one can be (remember, this is a guy who has been married twice already!) and it sounds like the mystery writer eventually wins Rachel over.

Lisa maintains that her character is "not an enemy of Castle's," but at the same time she seems to be taking her role as Beckett’s mentor very seriously."She gets who he is, but she also knows what her job is. ... McCord has made mistakes of her own, and that's why she feels qualified to help Beckett avoid doing the same thing," Lisa concludes.
