I actually didn't mind this episode too much - I like Blaine and loved the Duran Duran mashup. That said, I loved the "Someone I Used to Know" duet even more, as that's one of my favorite songs (kudos to them for adding a current song in there). And Blaine's brother is hot with a great voice. I actually sat there thinking I wish he'd be on the show and take someone else's spot.
I really enjoyed seeing Sue snarky but nice. The DS spin was obvious but I loved her interaction with Becky. I hope the "old Sue" is here to stay!
Hated the Quinn storyline and everything about it. There were so many messages (and even commercials) about teen texting and the worst they gave her was a compressed spinal cord that has a high probability of being fixed? Brother.
