The team did great especially in the circumstances and pretty much everyone has said.
Tribute aside, production wise Iain's v/o was bare minimum stuff, telling us what we needed to know and nothing more. Tomorrow night will show the result of a public vote that opened at the end of tonight's episode. Presuming that is filmed tonight, that's a lot of footage skipped cramming maybe four or five days into two episodes which is probably the right call.
Tonight pretty much centered around the fluffy stuff rather than some of the bigger conflicts that can happen (even the ones featured had their edges softened IMO). Imagine it will continue in this style for the next week, which given its the last week anyway won't be a huge departure. Be interesting how they approach the final which is usually live from the villa, given that the contestants currently are unaware of the situation.
I suspect for the bit where the parents/family come in, the show may try and break the news gently to the contestants then (or have the parents mention it) otherwise it would be a bit of an elephant in the room during the final.
