"So, you're not joking." He blinked momentarily, letting the idea of Puck and Blaine sink in for a moment. Puck was the ladies man, as far as he knew, then again well his fascination with anything from cougars to Lauren, Finn was pretty sure Puck was a sexual creature bound to end up with anything. Well he hoped not animals. Maybe he should keep his puppy away from Puck, his brain joked. Well, half joked.
No, the surprising thing was, that it wasn't that he was hooking up with a dude, which Finn really tried to get out of his head (I mean the same dude that was just with Kurt!), it was the fact that Puck was willing to destroy his rep to date a dude. This was basically world rocking.
Like to the point where some jock was getting pissed off at him for hogging the machine and he couldn't hear the guy yelling at him for like, totally forever.
"Oh, sorry."
Finn got up from the seat, taking a swig of his water bottle before grabbing a set of barbels.
