Big question is whether, if the MC slept with Elaine, the MC will listen to her explanation or will he run away and prolong the drama like so many MC's in so many of these games.I don't think it was Elaine, to me everything screams "setup" by Bella and Jo. Would be easy for Bella to lure her sister there and for Jo to make sure she got the cctv recording.
I want to see a giant argument between the two of them which could make or break their relationship. Not a "flee response activated" situation where the MC goes and talks it out with someone or stews about it before forgiving/forgetting her.
