Okay, my thoughts:
- Overall, it was a pretty entertaining episode. I enjoyed it more than the last two. The music was fun.
- Nice to see Mercedes and Mike actually get something to do this time.
- Katey Segal made a one scene walk-on appearance. This show loves squandering people.
- Always nice to see Burt (and Glee remembered Carole exists!), and he's reliably the Voice of Reason.
- which brings me to.....oh, Blaine. In what desperate, Kurt-fevered corner of your overgelled head does proposing marriage to your ex-boyfriend who you haven't been with for most of the year sound like a good idea? Despite Blaine's protests, Burt was right that they really would be pulling a Finchel, even assuming (a huge IF) Kurt accepted it. Blaine means well, but he's not mature enough to understand the significance of what he's planning, especially considering he cheated on Kurt after a few weeks of separation (Kurt was not blameless in the situation either, but still) and has spent half the time since crushing on Sam. Actually I think Burt could have hit the point harder, that Klaine isn't even together at present. Get a freaking grip, Blaine. Proposing to your ex who you haven't been with for months is insane. Seriously. Congratulations, you have gone leaps and bounds beyond the Gap Attack fiasco for the worst idea you have ever had. And the promos show you asking Sam to be your best man, so clearly you didn't take Burt's words of wisdom to heart. Hopefully the lesbian mentors have more of an effect on you (as I think they will, since we already have spoilers he doesn't actually propose, thank God, though part of me would like to see Kurt's expression if he did).
- So the writers remembered Cassandra exists, whom I honestly thought they'd forgotten about, only to spin her through the Glee Villain Insta-Redeemer. None escape its clutches, clearly. Her number was fun though. By the way, how is her wardrobe any kind of remotely appropriate for a teacher??
- Considering they made a storyline out of putting Finn in college, it's just lazy how they can't even be bothered to toss in some throwaway line about how he's MIA because he's busy studying for a big exam or something. Also, they've completely forgotten Joe and Sugar's existences, but they'll conveniently be back just in time for Regionals.
- I smell Funny Girl and Klaine as two of the big finale cliffhangers. Possibly Regionals.
