I was never a fan of Romil, but now I am and I will be rooting for Jasleen, Megha, and him as long as they stay in the house.
He is actually one of the best male contestants and the way he has been targeted, it does not look like he has been isolated as he is talking with people, behaving normally, and continuing to play his game.
He never used the isolation card as an advantage to receive sympathy from the audience.
Also, the way he promised that, he will always stand by Jasleen seemed so genuine and how he expects Somi to support him, he should realize that, Somi really cares about him.
