Well whatsisface who snogged Katya (I literally can't remember his name, lol) subsequently created a whole comedy routine about what happened and apparently used the phrase "her gay husband" during it. I always wondered if that was from the horses mouth I. E. Katya herself.
That said, Katya seems to have completely fallen apart when Neil walked so clearly there was a lot of dependance there. But on the other hand, people don't snog other blokes when they're blissfully content at home. So who knows. It's quite hard to tell what was going on there.
I mean if she was just his beard /Visa, then why was she so devastated and kept wearing her ring? It's a puzzler.
And I'm a nosy bitch, lol.
