Many say that Asim instigates Sid and that's why Sid gets aggressive with Asim. But during WKW many of the HMs accused Sid of passing by and passing snide comments and mocking and laughing at HMs. It was also evident in WKW itself, when Sid didnt even spare Salman.
IMO BB must have realised that HMs have reached their bursting point and that would only make someone like Shukla all the more obnoxious. Also Vishal and Bhau were the most irritated and if Sid would have stayed, Vishal and Sid could have had a massive showdown n unlike Asim, Vishal would have insisted for action to be taken against Sid by BB.
So in order to cool things down among the HMs, BB sent Sid to SR.
Also I'm sure BB will do the captaincy task in such a way that Vikas becomes the captain. Also Vikas being a proxy of Devo is a load of BS. Vikas is simply there to enhance a few HMs games.
