Missing Finn
She's fixing her makeup in the bathroom when Rachel catches her—ambushes her, more like. "I need to ask a favor," Rachel sets in, and it's obvious to Quinn from the moment the words come out of her mouth that there's no use disagreeing.
"What is it, man hands?" says Quinn without an ounce of spite, because she doesn't hate Rachel, not really. Anyone who could see past her lifeless insults would realize that.
"It's Finn," says Rachel purposefully. "Now that he's rejoined the football team, his renewed popularity, quite frankly, has me concerned, and I—" Her voice wavers. "It just scares me to think that… that maybe I really am just this loser who will never be good enough for him."
She's Quinn Fabray, so she tells her dryly, "Trust me, Berry, nobody is too much of a loser for Finn, not even you. You know I've caught him having avid conversations with Britt before trying to figure out the difference between right and left? You've got nothing to worry about."
She's Quinn Fabray, so she knows exactly how Rachel Berry feels. And here's the kicker: what she really means to say is that Rachel Berry is a shoddily-clothed control freak with a hell of a voice, and if the world is kind she'll go places one day, and a lovably stupid sweetheart like Finn will get in her way.
So she goes along with Rachel's plan, asks Finn out and reports back to Rachel dutifully—and she reinvented herself last summer, moved back home with her mother and traded maternity clothes for a Cheerios uniform, but the stretch marks don't fade. Maybe she never loved Finn to begin with, but it's a slap in the face that Rachel has him now and she has no one and it's all her fault (and it's all her fault).
It doesn't feel right to undo the past, but Finn says he doesn't want to go back, and that last bit of hope for her future that she'd been clinging to flickers out, just like that.
(Rachel sings adult contemporary to Finn the next afternoon, and Quinn entertains a daydream that she goes to Finn's house for sex and gets it. She wouldn't really love him, and he'd only love Rachel, but she'd miss him, and he'd be sad, and after everything, they deserved a night to make a fake baby together, didn't they?)
(She stays at home, curled up on the couch with a tub of Ben & Jerry's and an old Grey's Anatomy DVD, and she can't quite decide whether she regrets it, or which part of the last year's train wreck is the right part to regret.)
