Andi Dorfman Returns to 'The Bachelor' to Confront Nick Viall -- But What Does She Want?

'Hello, Nick.'

Nick Viall got a surprise visitor on Monday's episode of The Bachelor, but whether or not she receives a warm welcome is up in the air.

The brunette beauty behind the door was revealed during this week's episode to be….the one and only Andi Dorfman!

That's right, Andi made her grand return to The Bachelor with a stunning "Hello, Nick," one year after releasing the tell-all book that slammed the Milwaukee native (and right before he picks his final three) -- but what she's after is still unclear.

While Chris Harrison left us with a glorious "to be continued," the episode didn't end without a super juicy preview teasing what Andi's surprising visit means for Nick.

"This was very unexpected. What am I supposed to say?" Nick dramatically asks to the woman "who broke his heart."

"You're supposed to be honest!" Andi yells back, before casually sipping from a wine glass.

"I mean, this is blowing my mind!" Nick confesses before revealing his biggest fear: to end up alone at the end of his journey to find love.

"I'm not sure what's going to happen. I have a lot to think about, and I'm running out of time. I have fallen in love twice here, and I've had my heart broken twice," he says. "My biggest fear is that that will happen again. If I was the first Bachelor to get rejected, I'll be devastated."

But alas, the final rose is still weeks away, so here's everything else you need to know about this week's episode.

Raven's dad is officially cancer free, so she and Nick celebrated with a muddy make out session. (Just kidding, they got down and dirty before hearing the big news, but still, what a day!)

Rachel's dad was too busy #judging to actually judge Nick, so her family stepped in to ask him the hard questions, like whether he's ever dated a black girl before (the answer is "no, not seriously").
