The much awaited consummation will happen ! I am 99 % sure it will happen. He will go back to the kidnappers only after the consummation. As someone said in the post earlier, it would be so silly if those "Good for nothing" kidnappers break in at the time they are having their moment. And if you watch SBB carefully (like I did - freakin 10 times already) 😆 and listen to each and every word the reporter is saying, it leads to only one conclusion that the consummation will happen. He will go back to them while khushi is still sleeping in the morning and then when she wakes up she won't find him there and her hunt for ASR will begin again but this time along with Mami and NK. 😉 Or Arnav himself will tell khushi in the morning to go back home and he will be back. They might plan out something together in order to find out who the kidnapper is and why he or she is doing everything.
