Surely the Horton's will be ringing to speak to Tommy and he'll mention all the people in his house and his new bedroom buddy Tyrone
I'm thinking they were prob expecting Jack and Vera to sleep in one of their very many guest bedrooms and not their own bedroom as well
So one bedroom J&V, one T&T, one Maria and one G&the twins. (tight squeeze) and one converted bathroom. That’s a very large house
