Puck knows nothing about women. Except that they are absolutely fucking insane.

He knows that they don't see him, standing aloof in the shadows behind a set of lockers. (As if he's actually going to class when he could be out drinking whiskey on the bleachers.)

She looks like a fucking goddess, golden curls wound loosely around her heart shaped face, little sins waiting on the perch of her pomegranate pout, alabaster skin unbreakably smooth. Stalking like a tiger for her prey, she arches one eyebrow over the ivy orb and lures in her victim with the birth of a grin.

The victim in question blossoms with a huge smile stupidly crossing his features. Baby face lit up like he has no idea what the hell is happening. Dude is fucking trapped.

And then she goes in for the kill. He doesn't need to see this. The conception occurred in front of his very eyes. He doesn't need to see the birth and death all at once.

Two days ago at the conference game, when Finn scored the winning touchdown, Puck watched in horror as Quinn locked eyes with her ex and time transported them back to last year.

(The only thing that hadn't changed was the grimace twisted on Puck's mouth.)

Sam is okay dude. He thought that he would want to plow him through a wall when his stint in juvie was over, but the kid is actually good for her. It's something that neither him nor Finn ever were. Sam walks her to class and holds her hands and keeps the promises that he makes. But he's also a badass, stands up for what he believes in, defends his friends, and Puck, he can respect that.

Though Puck is the biggest violator of the bro-code, he respects what it means to other douche bags, and he's pretty sure that Sam wouldn't think it kosher that the former quarterback and head cheerleader were panting over each other. Again.

Plus he knows how hard it is to get over Quinn Fabray. (Mostly because he hasn't done it yet.)

True, he doesn't see the lip-lock, but he knows it happens. Finn's intelligence level is somewhere akin to a box of rocks. Quinn knows it and thrives on it. And the past is bound to repeat itself. (Hopefully he doesn't knock her up again.)

He knows the repetition is inevitable when he's strumming guitar in front of the club, singing in harmony with Rachel while he gazes out the corners of his eyes at Quinn.

(Sometimes he thinks that him and Finn should be fighting over Rachel.)

And apparently they're back full circle except roles have altered. Quinn is still the icy bitch with the caramel surface deceiving every guy that crosses her eye line. Finn is now Puck, bless the poor bastard. And Sam is cast as Finn 2.0, a role he's been trying to avoid since he landed here in August. Rachel, well, she's back to pining for Finn 1.0 without any kind of success on the horizon.

Puck knows the rules and the story, how it goes and what happens to whom and the one that gets the girl and the one that ends up on the bleachers with a bottle of whiskey.

He just hopes Sam is up to sharing. And that he gets a better role this time around.
