See, here's the thing. This episode would have made so much more sense in its original place (which was before Theatricality, last week's episode) because it does explain quite a few little things in there. It does seem like there was a whole mess of continuity between the episodes though which...I just don't get how it happened. Quinn and Mercedes being together with Rachel when they were spying on Vocal Adrenaline makes more sense from this week's episode (although those two have grown closer throughout the second half of the series, but especially so this week). Vocal Adrenaline not really being on it throughout their GaGa performances makes sense thanks to this week's episode. Jesse not being in the Glee Club too, which the "previously on Glee" completely got confusing on...yeah, my head started to hurt during the episode a fair bit. Quinn didn't look as pregnant as she did in this episode in the last one though. So, overall - ugh, confusing Glee continuity >_<
Still, I thought it was a good episode. Nowhere near as good as the last two have been, but I think they were far beyond the average Glee episode anyway. I love Dianna Agron's voice, although the song wasn't particularly suited towards her, but...yeah. More of her singing, please. "Loser" was awesome though, plus it's always nice to see Sandy/Terri/Howard around. Terri and Finn's idea to just type in "funk" and assuming that'd lead to a funk song was a great little gag too, especially with what it resulted in.
