Why is Vikram doing this?

Today we saw Vikram ringing Aditya in the middle of the night for no apparent reason. Why is Vikram doing all of this? Drinking alcohol infront of Aditya making Adi feel that just because he is drunk he doesn't know what he is saying.

I feel he is going to bribe Adi completely by saying "you are from the girl's family so you have to listen to me" statement. Aditya is falling for it right now but I feel he will start to fall suspiscious very soon. He is already thinking about his nature from his expressions and I am sure he will share it with Pankhuri. But the real question is will he stay quiet because of Kaira? Kaira is now married into that house and suppose he does find out about Vikram he will try and save her but he has to be very careful with what he does and says. Afterall, one wrong move could lead to more problems for Kaira.

With Vikram's very straight forward response about the curtains in the precap will Kaira also fall suspicious about his true nature?
