everything about it was fake. they were filmed visiting properties that were completely non-starters for them, they were made to say positive things about the houses that they didn't agree with at all, footage was edited so that things they said at and about one house were made to look like they were at and talking about a different house, and in the end the program said they happily bought one of the houses, when in fact they never even made a bid for it.

as most people do, i imagine, they didn't stomp their feet and chose to just go along with it because whatever, they're on tv, so what if it's in a fictional show instead of a non-fiction show.
