He knows, there is no way he can fool her.. he can fool his mom.. but not her! She being with him for soo long.. knows him inside out! I mean.. things we dont share with our parents, we would, to our significant other.. and I feel, more than lovers, they were like best friends. Their cute nok-jhok in the beginning showed that!
So yah, him revealing himself or not.. he knows, Twinkle would know him. Thats why it was like an 'open challenge type thing' for him.
Looking at the precap though.. wonder what Twinkle was talking to Kunj about, and for what she needed him to believe her. Hmm.. 🤔🤔
