re who comes back (speculation):
Spoiler:
Tatianna's reaction in the teaser is quite strange because it looks as if she's being told she's returning. I don't know why else she would be so happy.
I could be completely off with that judgement, but the fact that she tweeted 'It's all good! Trust
' makes it seem quite obvious, unless it's to throw us off. Oh god, maybe I'm looking too much into, lmao.
