Outside, Wes is proudly saying he's never cheated once in his thirty-two years. To paraphrase Chris Rock, you're not SUPPOSED to cheat? What you want, a cookie? And then they're making out before heading back inside and interrupting a discussion of who the other guys think are going home.
So then Jillian goes off to talk to Jake, who says their one-on-one date was awesome, and he got really excited, and time has gone by and it cooled off, and he was disheartened to hear her say on the boat that he can be himself with her. "This is me. This is Jake," he says, and she seems a little bit confused about why this is a problem, and then he talks about how much more of a man he is than the other boys out there and he doesn't really relate to some of the things they do. Then he talks about how he doesn't want to throw anyone under the bus, but she need to be really careful about who she lets go, because there are guys there who aren't there for the right reasons. In other words, he wants to throw someone under the bus, but is actually too chickenshit to call someone out on their bullshit, but plants a bug in Jillian's ear and then doesn't get specific.
Juan comes in to take Jillian, and then Jake goes back out to talk to Ed and Tanner about how they hope Jillian sees through all the non-awesomeness of the guys who aren't them, and Tanner says something about guys not being there for the right reasons. You mean like feet, Tanner? He says he's going to lay it out for Jillian. He's not here to make friends, and if he makes enemies, he doesn't give a (bleep).
So he does sit down with her and tells her some of the other guys are being fake and not sharing with her their real lives or whatever. At first she seems to think he's just talking about the differences between how people act when the cameras are on and off, so he gets more direct: "I hate to break the news to you, but I have honestly heard guys say, 'I've got a girlfriend back at home.'" She's upset by this, and says she doesn't want him to rat anyone out, but "does anybody care enough to tell me who these people are?" So she doesn't want anyone to rat anyone out, except she wants someone to care enough about her to rat them out? Whatever, Jillian. In her annoying quavery half-crying voice, she babbles about how she's been hearing about this bullshit all night, and her conversation with Tanner was the last straw. She's worried about falling in love with someone who has a girlfriend, I guess.
