The Bachelor star Ben Flajnik is going to woo -- and be wooed by -- this season's three remaining ladies on Monday night's episode. And it's set in Switzerland!

Flajnik must endure more dates with Courtney, Lindzi and Nicki to help him determine who he will take home to mom.

All the stuff I've had to go through to get to this point, it's worth it, he said in a preview clip.

By the looks of it, one of the old contestants comes back. It's no shocker, really. Former contestants -- some of whom were dumped, some who did the dumping -- tend to make cameos as seasons draw to a close. One example is DeAnna Pappas, the star of season 4 of The Bachelorette. She showed up during former suitor Jason Mesnick's turn as The Bachelor. Remember: He competed for Pappas' heart and made it to the final episode only to be dumped by her after he got down on one knee to propose.

Flajnik looked shocked to see his own blast from the past. So shocked, in fact, that his verbal reaction was bleeped.

Snippets of Monday night's episode also show that Courtney has an exchange with Flajnik about all the commentary he's been getting about her from other contestants throughout the season.

The thing that worries me is I don't want you to feel like I'm being fake, Courtney tells him.

It's hard for me to hear those other things, Flajnik admitted.
