Gina and Dexter in the safe house. Just everything to do with it really. The fake evictions, them being told, how close they got(or seemed to get), the fun they had etc etc
Edit. thought this was best moment of the series
Daley ejection + the whole safehouse stuff, though it was horrid to watch even from the first night. I actually feared for Hazel from the whole shower thing and then on, seemed obvious it was gunna go wrong
Race card
Callums demise (again uncomfortable to watch though)
Michael, though it could have been so much better
Race card thing
Having live feed back and actually seeing the fun moments. We wouldnt have seen any of that with just the HLs
