Not the best nor worst episode. I don't usually care about realism in my escapism but just wondered how the younger brother, (Clifford?) went from being shot in the chest to going into witness protection, up on his feet back at the precinct in what appeared to be two to three hours? The wrapup was a bit too predictable, the emotional payoff was weak. That said, its Castle and its generally good entertainment. I am starting to weary, tho, of the lack of development in Castle's at home scenes. Bland.
