DH thinks that Amy was definitely The Other Woman and that the guy built the annexe for his parents to get them back onside after a big family bust up over the affair
I've just watched it and that was my thoughts exactly, I thought Kevin alluded to that at the start, he made some kind of comment about the guy's life being turned upside down when he met her.
I thought there was a really weird dynamic between them all, the couple, and the parents. I wondered if the parents had to dig him out of a financial hole and that's how they ended up living in a caravan.
Not keen on the house, looked huge from the outside but a really strange use of space inside. It should have seemed really spacious but felt quite boxy and each area felt small.
Plenty of hazards for a toddler, those stairs, the baby gates on the stairs had gaps wide enough for a small head to get through and then get stuck, that little balcony thing that Kevin was looking over, that pond in the front garden unfenced
.
And that bath in the main front window that everyone can see from the road - what were they thinking?
