According to a recent spoilers round-up from Watch with Kristin, there isn't much to say about Puck and Rachel (sorry, Puckleberries!)...but there's definitely something to say about Kurt (Chris Colfer) and his future
boyfriend, Blaine (Darren Criss):
There hasn't been a lot confirming "yes" or "no" as far as Darren Criss' upcoming character, Blaine being a possible love interest for Kurt (they're going to start out as "just friends"). But we're getting closer, Kurtsies! They. Sing. A. Number. Together. Can't get much better than that. At least for now. Oh, right...you want to know what the song is. "Baby, It's Cold Outside".
