1. the gang had played pranks on him wen he just entered college.so this may a friendly revenge.
2. everyone gets a message from adhiraj's cell to come at that place,whereas adhiraj says he got a msg from mayank.he could have lied.
3. wen he calls that number from his cell,it is not in use.
4. during truth n dare at mayurs plc,he excuses himself during gunurs turn saying his cousin is going to call.so may be one of the two of tanaaz-bakhtiyar may be his cousin.
5. also wen he and d4 are sitting in the camera room,he is nicely putting his hand on d4's shoulder as if he knws him frm b4.
6. another thng,wen the guys cum to dia's plc for dinner,al the boys proceed but adhiraj is shown answering a call.so may b he is calling d4 as samrat gets a call frm d4 sumtime later.
i think so..............wat do you think guys?i wish the suspense cums out soon.
