Everything Happy Club attempt to do something nice, they are accused of being "mahaan" but then in the Friday ep (mine's a day behind), both Dipika and Jasleen gave the bands, and Dipika's in particular was highlighted.
This was the same Dipika who was cheering when Happy Club was nominated and same Jasleen who was being mocked and was angry with them. Jasleen even laughed at a couple of Romil's jokes. No one really questioned their intentions as much.
Deepak running back to Sree, telling Surbhi "I like him but I don't trust him in the game", and then spilling their game plan for captaincy task. There is some weird attachment or respect between the house members and Sree.
I think we are not given the full picture in BB, that the housemates do get along some times but fights are shown instead. There has to be some interaction going on behind the scenes or maybe I am just petty.
I don't Happy Club are "fake" nor did I think Dipika/Jasleen were doing it to appear "mahaan", though I didn't get why she didn't do it together with Jasleen.
Just think we don't give housemates, especially Happy Club, the benefit of the doubt that they do like each other on some level.
