Shounak , I don't think Ishan is going to turn in to another BP . But at the same time that scene made me think , where this is going ?
Ishan knows & understands the damage BP has done so It will b very hard almost impossible for him to do what BP has done in the past. It is not in nature of Ishan that He will knowingly hurt anyone . but that said . He can or may hurt UNKNOWINGLY . There is possibility of that .
Ishan wants to achieve something in life , become someone in life . But will he b CONTENT with what he will achieve or wants more & more . It is possible , When U r successful in one step of life , U want to start climbing the ladder thinking , I'll stop here but U never stop & think When It is enough . or How far u want to go . Time will tell , But I think somewhere in those high successful days , Ishan will realize what is the most important thing in their life .
Some people know What is IMPORTANT in life from the beginning & some goes through Hell to find that out . As for Isha is changing & for better or for worst , V'll learn it later on . If they r going to show the story as Ishan's hunger for name ,fame , success then Yes , that is how It may end . But I think In the end Ishan will b back with Kashyaps . Cauz that is where he belong .
