may be its raj......i know i hate myself for writing this but i think aryan and mallika are too obvious choices so it has to be raj .....maybe he thought of killing/injuring armaan but instead hit jassi ......i wont be surprised if t&d act do this .....coz they have been showing raj denying the other day that its jassi and still has feelings for arman and also last time he act videotaped jessica remeber ........maybe t&d did all that for a reason ...a dumb reason like this to move forward the show
god knows what next
