Castle has been an idiot sometimes in the latter half of this season, what with him being undecided over choosing his precious video game or a horny Kate. Still this is to be expected of him. Although Rick has matured a lot over the years spent with the NYPD, he still retains that air of a bumbling idiot/silliness. Kate spent 5 years with him before finally doing the deed & hence she knows him best..hence my disapproval over her behavior after the above-mentioned 'video game' incident. - She almost gave into the charms of a billionaire playboy while in a relationship with Castle. If she could deal with the advances of Castle (who not only was a ruggedly handsome millionaire playboy but also her favorite author who's novels helped her get over her mother's murder)at the start of Season 1 despite being single for over 5 months, how come she almost gives into Mr. Vaughn (she did let him kiss her on the lips) while being in a relationship? Was she feeling lonely & bereft of attention...just because Castle kind of ignored her for 5 mins? Please! That move went totally against her nature. That whole episode should have been written differently as it's not like Castle's nature either to ignore Kate..who is the center of his existence along with Martha & Alexis. Writers mistake. Andrew Marlowe should not have let this happen cause quite a few faithful Castle fans were let down big time..including me, particularly as the episode "Still" was designed to be aired before "Squab & the Quail" (but was eventually aired after due to the bombing incident) where Castle literally decides to die together with Kate.. .not exactly an indication that he was already fed up with Kate & ignoring her! - The real problem with the job offer that some fans missed was the fact that Kate took it behind Castle's back. It meant that she did not really trust him & that she didn't have total faith in her relationship with Castle. Despite what Martha said, Kate had second thoughts not because she didn't have a ring on her finger (which was some real stupid advice) but because it was in her nature to be doubtful of everything. Plus she was acting out of character too. Yes Castle is a rich author who can write from anywhere. But his problem was that Kate didn't confide such an important decision with him, whereas Castle has been asking advice/discussing on practically every major decision he took (even Alexis's boyfriends) even before they were in a relationship. - Ultimately though Rick & Kate managed to work through this huge mess & Kate's distrusting nature to end up getting engaged, which would only make their relationship more stronger.
