Baby Buyer calls Juliette a good friend, stood up for her when the lovely Colin was addressing (in private, with him) Juliette's behaviour at the last dinner party. That's enough for me to think Baby Buyer is a wrong 'un. Juliette = Gia's puppet, therefore also wrong 'un.
I've already seen some spoilers as it's finished screening in Aus (not sharing) but find I really don't care enough about pretty much any of these self absorbed, attention seeking people. The producers have messed up badly, I feel, in not finding some "real" people, some good eggs, couples that we want to cheer on over the final line, in this series. Rachel and her continual statements of how hard she and Stevo have worked at their relationship - if it's that blooming hard babe JUST GIVE IT UP. It shouldn't be hard work.
Cam and Jules from series 6 - they'd never have found each other independently without MAFS. And now married with kids. There's others too from other series which makes a nonsense out of this years mob of wannabe actors / Only Fans participants.
(I don't want to be spoilery if some people don't want to know.)
