I do think Georgia has just been hoisted by her own petard. The producers just gave her the rope.
She's unable to say now she's not that into sam and she made such a thing about how she was and how she was loyal, it makes her a liar if she says it wasn't real.
I think she was basically telling Dani, when she was saying one she could have fun with etc, and that's why Dani reacted badly. She didn't like it. As she'd believed Georgia about sam. She said they'd been talking about double dating.
Sams fucked, he really liked her and did the gentlemanly thing and tried to protect Georgia, as well as make it look like he wasn't being mugged off, by saying his decision, but it obviously becomes clear he has been.
It's like when you know you're about to be dumped, and get in there first. That's what's going on with sam.
