Charlie and Eve got on at the wedding and slept together. After this it appeared that Eve lost interest.
Eve refused to sleep in the same room as Charlie since the first night. There was a big row on the final night of the honeymoon where Charlie threw her ring away and shouted at Eve.
Eve was completely checked out from then on. She refused to participate in the tasks and kept accusing Charlie of shouting at her, even when she wasn't and walking away.
It turned out Eve was telling the rest of the girls that Charlie was bullying her and it ended up with a Polly intervention where she confronted Charlie at the dinner party and really upset her. Eve denied saying anything.
When Charlie was filming her confessionals later Eve was eavesdropping at the door. Presumably to hear what was said and refute it in her own talking head.
At the commitment ceremony Eve denied eavesdropping but was called out and footage was shown.
They both said leave snd Eve was never seen again.
I think that's it. A lot wasn't seen on screen so it's hard to work out what went wrong.
Ever since Eve
