Preface: I think Marie is a nice lady and I have no issues with her, but this is a question that I have that I don't know where else to ask...
Yes their house is super small, but:
a) didn't they have some kind of annex that her mum used to live in? I believe Louise stayed in it one time while visiting?
b) that little room off their kitchen. The last she showed it was like... 4 years ago (though I don't watch religiously, so could have missed something) but it was just basically used as a storage room. Could that not be a bedroom for one of the kids?
This is just curiosity, not shade.
