It was so cruel to send Fahmaan as a wild-card, and then pulling an April fool's joke on November saying haha he's actually not a wild-card. What was the purpose of that? They could've just introduced him as a guest who has only come to stay for one day. That way Sumbul won't have raised her expectations.
Sumbul was so happy to see her friend. She had a panic attack and was feeling so low the very same day. Fahmaan coming to her aid must have given her hope, only for that hope to be crushed later on. She looked so heartbroken when told by Salman that Fahmaan is not a wildcard and he has just came to promote his show.
Also this looks very pre-planned. Her father too mentioned Fahmaan during the call with Sumbul, only for him to come to the show the very same week. This whole thing seems very scripted and pre-planned by Bigg Boss, Sumbul's father and Fahmaan.
Fahmaan seems to be another person in Sumbul's life who is exploiting her like her father. What kind of friend he is to play with Sumbul's feelings just for the promotion of his new show? He just came in Bigg Boss to promote his new show and doesn't seem to care about Sumbul. Looks like everyone in Sumbul's life is using her for their own benefit,whether its friends or family. No wonder she has so many issues!
