I think this is about the night ShaTina-Nimrit were dissecting Priyankit's relationship. Sumbul bich mein aake unko updates de rahi about whatever Priyankit had told her about their personal equation (Tab Sumbul used to stay with Priyankit a lot, mostly Ankit).
Tina was talking about 'Chati(chest) pe pair rakh k baithti hai' etc. Sumbul bhi thi usme involved along with Nimrit.
But Sumbul-Nimrit k words nahi yaad. Except for Nimrit's 'Mujhe lagta hai meri aur Ankit ki vibe achi hogi, I think I can have one-on-one talks with him' 😆
