If he has a 'brain stroke' and after that not only regains his memory but also plans to trap Ayesha by pretending to still have amnesia, then that 'brain stroke' must really be something. Normally a person is incapacitated after such a stroke, losing motor skills, speech or vision and suffers from paralysis. But I guess in BT world anything is possible. Milsi atleast has been shown to be super human.
He has escaped a horrific accident involving iron rods which pierced his car's windshield and came out unscathed. He fell from over 500 feet high into a stream less than 5 feet deep and managed to survive. He had a miraculous recovery from a brain surgery and was walking down the hospital corridors within hours. He seems to have suffered from four head injuries (one in Turkey and three in India) and the man is still walking around with just a guaze on his forehead (which by the way enhances his looks).
