I read earlier dont remember where that he has some kinna mental disroder. To me he looks fine mentally but has a speech disorder. Despite all that he sings well and sings a lot better tha myself and millions others. I hope people\judges vote him for his singing and not for his speech disorder cuz that wont be really helpful to him - and more importantly it would be unfair to Debojit himself. Kinna dont like this white T-Shirt :S Are they trying to make him look like he is mentally challenged?
At the end of it it looks like "Music Thief" Pritam is the one having speech disorders and looks mentally challenged as well :D
