She said she never imagined that they would phone her up.

However - what did she imagine the film crew were doing in her flat whilst she took the call? Popped round to borrow a teabag?

Maybe they told her she was going to be on Gogglebox?

Maybe they told her before then she got told to act shocked receiving the call ?
lol it seems weird for the film crew to already be in her house.

Looking back, I honestly think she knew she wasn't gone as she seemed so cool and calm last week

I'm glad she's back but why not just put her through to start with?
