Behnein actor Sudeep Sahir has been having sleepless nights for the past four days. The actor has been continuously shooting for the show and is doing all he can to get into the skin of the character. However due to lack of sleep, during a sequence in which he had to hit Karan Mehra with a flower vase, he accidentally ended up hitting his co-star Shiju Kataria. So involved was he with the performance that he did not realize it. Later he saw the scar on her forehead and rushed to help her and apologized for the same. Needless to say the scene turned out well.
