Saba is a very supportive sister who wants her sister to do well and their love for eachother was visible, they still tried laughing while crying, that was the ebst moment for me. Khan Sisters can do anything for eachother especially Saba, Saba is hard fir everyone else, but for Somi, she can give up on everything, nothing matters for her more than Somi's happiness.
Somi treated this like a task and she even said when Neha , Sreesanth, and Karanvir went to jail that, you cannot take your own name for anything.So she stood by her statement and did not take her name, she wanted to fight for her place and she expected Saba to do that also, but Saba gave up. Somi also was crying geniuinely,so she was not being selfish, but was in a competitive attitude where she did not wanted to portray herself as treating Saba differently than her other housemates, she wanted to be fair
