Also, Deepak has backbited alot about Khan Sisters, so where is this coming from, if Deepak could not be loyal with Urvashi and even Surbhi where he did not support her when the smoking incident took place, he went by the majority.
Deepak is not interested in making relationships, but he only cares about himself whereas Somi is definitely a loyal person who sincerely maintains her friendships and keeps it a priority just like Saba.
Just because they have not got any lovestory this season, that does mean they can just make false rumour about two people together who are just part of the group because of their friendships with Romil and Surbhi. Otherwise, Deepak has always been against Saba and Somi and always wanted to send them to jail in kaal kothri.
