The same scene also introduced the audience to Blaine (Darren Criss), quite probably the long-rumored love interest for Kurt. The bond between the two was instant, and it's a light at the end of the tunnel for long-suffering Kurt. Criss impressed audiences and producers alike, and is already being wooed to upgrade to series regular, likely to kick in at the start of season three next fall, which is already ordered.
The third thread of the homosexual plot involved a school bully who has been picking on Kurt. To be honest, I couldn't tell if it was one of the same guys who has slammed Kurt into lockers before or not. It's always possible that he could be Kurt's love interest instead of Blaine, but I doubt it. There could have been an interesting story there, but with Glee's already huge ensemble, it's probably better that the guy just disappeared into the background.
In other news, Puck (Mark Salling) made his not-so-triumphant return after spending the last two episodes in juvie. Before the ending credits, he was already facing serious trouble, including a return to lockup. Seeing Puck the rebel was a departure from the tough guy who came off as almost sweet last year as he tried to step up and take responsibility as a father. It was an unfortunate backslide, and one I hope will be corrected. Unless they're just ready to dump someone from the cast, and he's the choice. I'd be OK with that, as it's got to happen no later than the end of the season, but I'd miss him.
Speaking of the too-large group of players, will they ever reveal what grade the students are in? I'm guessing that since Mike Chang (Harry Shum Jr.) remains the only original club member not a series regular, he's a senior. Someone has to graduate. I find it semi-believable that everyone returned for season two (except one guy, who was said to move, not graduate), but surely they were not all freshmen? Puck, Artie (Kevin McHale), and Tina (Jenna Ushkowitz) are the primary candidates in my mind. I'm not really ready to let go of anyone else. They cannot all possibly return for season three, unless the show follows them to college. Which would be awesome, but again, way too many people to share screen time already, and a new setting, with inevitable new characters, would just add to the mess.
