Back from commercial (after the rules get explained to us again), Michael explains AGAIN their plot. They desperately need Erica to think Michael and Rachel voted for Lindzi, not her. In a conversation with Jaclyn, Erica finds out Chris is voting for her. She goes to confront him about it, and he tries to stick with the story that he's voting for Lindzi, because he's too dumb not to realize what an implausible cover story that is. But not even Chris is too dumb to know it's not in his interest for Erica to know he's voting for her. She warns him that if she's leaving, he's not safe. Then, after finding out from a couple more people (Michael and Ed) that Chris is targeting her, she ups the ante but telling Chris that if she goes home, she's definitely taking him with her.
She has a heated conversation with Sarah (and we have the benefit of knowing Sarah is lying) and they decide they're not fucking friends at all.
Chris seems to have forgiven Kalon enough to sit and wonder how this is all going down, and how to convince Erica that he's not voting for her. Kalon suggests taking Erica into the voting booth with him, and Chris laughs, before going, "Heyyyyy..."
And that's what he does (telling Erica they're making "Bachelor Pad history" like that is even a thing). So now Erica is mad that Michael lied to her, and Michael's foolproof plan is falling apart. She has now upped her threat response, telling the contestants that if she goes home, she's taking the whole house with her. She's going to torch the place!
Everyone gathers for the Rose Ceremony, everyone feeling uneasy, and not the unsettlement that most sane viewers have every single moment watching this show. Rachel says if the woman who leaves takes Michael with her, she won't speak to them ever again. (But naturally it's fine for Michael to try to orchestrate someone else's ouster.) Erica tells us she's livid. It's always best that Erica tell us what emotions she's feeling, since her expression never changes and she speaks like she's just been chloroformed.
So: Blakeley, Tony, Jaclyn and Kalon are safe. So who are the women who are staying? Sarah and Rachel, not a surprise. It's down to Erica and Lindzi for the final rose, and it goes to Lindzi.
