I have a theory that Noirin and Isaac aren't really ex's at all and got back together at some point before she entered the house.

Noirin has said that she didn't have sex for 6 months until 'just before' she went in the house'.

When Isaac came in she didn't even look very shocked, as if she knew he was coming in at some point.

Isaac is a professional reality show star and her whole performance, cock blocking all the guys while constantly mentioning her ex, could all be part of their plan for her to stay in the house longer/get the most air time.

I may be totally wrong but it's just a vibe I'm getting from the whole thing, and it totally would not surprise me.

What do other people here think? A possibility?
