On the one hand, the characters on Glee are in high school, and it stands to reason that they're all struggling with their identities, so their actions, motivations, and personalities might not always be consistent. That being said, the ending of "The Sue Sylvester Bowl Shuffle" bothered me more than any other episode in recent memory. The kiss between Finn and Quinn seemed completely out of character for Finn, and, to a lesser extent, Quinn. I would think that Finn, who is still hurting over Rachel's betrayal (with Puck, of all people) would be less swoony and responsive when Quinn (who is still dating Sam) kissed him, especially when you consider that it's Quinn's fault that Finn has a gaping sore spot when it comes to Puck and his girlfriends in the first place, since she cheated on Finn with Puck and had his baby. I guess we're supposed to assume that a few months' time and some glee club bonding was enough for Finn to forget why they broke up in the first place? I also expected more from him, seeing as he knows better than anyone how it feels to be cheated on, so why would he partake (seemingly without hesitation) in Quinn's betrayal of sweet, adorable Sam?
Yes, this is high school, and a certain level of short romantic attention spans and partner-swapping is to be expected, but at this point it really feels like Ryan Murphy is just abusing his power as the Puppet Master and throwing characters together in whatever arrangement he feels like on any given day, without much consideration for the integrity of the characters or storylines. I'm happy to be subject to Ryan Murphy's various whims (it is his show, after all), but I wish he would execute them in a way that kept all the characters intact (or better yet, showed some growth), rather than making them all seem like nothing more than sacks of hormones who continue to make the same mistakes.
