Just finished watching the episode.
The guy who was helping Mhatre just walked into the Sippy Mansion and bumped into Rohit.
Earlier on in the episode Veena mentioned that Vimmy has gone to her brother's house. And this guy mentions his sister to Mhatre.
What if he is Vimmy's brother? Also, Vimmy said her bro is getting married.
He is definitely related to Vimmy somehow because no other help in the Sippy house gets as much footage as Vimmy. And this man is obviously not here to meet any of the Sippys; they are too high and mighty to be associated to someone like him.
