I think from first look the girls will definitely say something to her about the way he has treated her and to have some self respect and not go back there. She does tend to listen to the girls.
And it was clear he wasn't talking about amber, as he said, "I've found what I'm looking for and she's leaving" so that will be called out.
If she doesn't pick him then he could go. And gregg stays. But Harley might pick Michael over Chris . And Chris goes. Or gregg over Chris.
So really I think it's between Chris, gregg and Michael who goes tonight. Depending on what amber and Harley do.
