Andi Dorfman arrived unannounced at Nick Viall's front door on Monday night's episode of The Bachelor, and now we finally have an idea of what she's after.

In a promo for next week's episode, Andi and Nick sit down for a not-so-chummy visit.

"Andi is the last person I ever thought I would see. So, what the f**k is she doing here now?" Nick says to the camera, as he invites Andi into his hotel room for a drink.

Nick doesn't have to guess for too long, as the former Bachelorette star gets right down to business, confronting Nick about his infamous After the Final Rose fantasy suite reveal.

"Do you look back, and you're like, 'Damn, I shouldn't have said, 'Why would you make love with me if you weren't in love with me?'" she asks.

"Super weird," Nick says, clearly flustered. "This is blowing my mind. I mean, last time you knocked down my door, you broke up with me."

"Oh, that's true!" Andi muses.

"You dumped me on national television," Nick repeats, giving Andi a run for her money in the sass department.

"But now, you're dumping 29 girls," Andi says, before Nick delivers an even bigger bombshell.

"I know, maybe 30," he reveals, insinuating he might not hand out his final rose to anybody.

….uh WHAT?!
