From the little Pre-Cap, it seems Paras was "evicted" and that's why Sana "Cried" . I also think the eviction is fake, BB would never let go of someone who disrespectful and vile.
Paras probably went to Secret Room, and this is probably BB's twist. Two reason that I can think of are:
1. Sana said she would never talk to Sid if Paras leaves. And BB probably wants to play that angle and see. This is absolute BS as well, because everyone knows Sana is a histrionic and needs male attention; there's no way that she would cut connection with Sid, because that's her source for limelight.
2. Paras is providing content, as gross as the content is. He plays devil's advocate. BB probably wouldn't take someone out like that, at this point in the show.
Thoughts?
