I think its angie all the way. She mustve asked ridz to get the propanol ka bottle. Obviously Ridz wont tell Dr. Kirti that her dearesst di is at fault. Angie prolly wants the intern of the month so bad that she cant get herself to accept her fault.
I think Kirti will get it out of armaan coz she heard him tell atul....and ridz might stay quiet and take the blame. She will prolly not tell armaan either and he must be mad at himself/ridz for letting all this happen.
confusion galore !!
