Yeah, Sara did take a level in badass last season, back up to where she was before she became Ms. Emo. I don't even mind that she's not full time, seeing as the purpose of her being there was to be filler until a replacement for Riley could be found. Although it is a bit of a plot hole that no one has called Catherine out for not looking too hard (she obviously wants Sara back full time). These kind of plot problems are the most infuriating. Some plot holes just can't be filled, but can be overlooked if the story is good enough. But those problems that could be closed up with one or two throwaway lines of dialouge that add about 1.2 seconds to the show's running time, those really piss me off.
