So Blaine has been busy lately. That's why he wasn't able to return any of Puck's phone calls. This is pretty much self explanatory. 

ps: I know his face his kind of blurry but I don't see why that's a downfall. I mean, it's still hot. And I couldn't do a thing about it. It's a photo that FFMAJM suggested me and it comes from Darren's instagram so yeah. Thanks btw buddy for sending me the pic. As you see, it was useful ;)
