Wheelchair part, since Shaurya can walk and usually maniacs have the strength of 20 oxen, so he might have lifted the wheelchair and brought in into the house. He must have injured or killed the servant as well so he wouldnt sound the alarm.
With the forced early end of the show, all logic has flown out of the window. Now its only sensationalism, sadism, loud drama, forced romance and villains hogging the show, good people dying.
At this rate, I will be glad when the show will be over and no more sadism will be shown in the name of portraying evil demons like Shaurya.
