He is acting all good in front of all and back bitting behind them.
In the task shown in LF, màjority are picking him as rocket for his fake and double dholki act(kyunki woh bahar se sab dekhke aya hai). And he has chosen abhinav as rocket to pump him (as he manipulated him to give up the captaincy and put him in the jail through sweet talk). All the contestant are falling for his fake careness and goodness.
I hope BB expose him or contestant themselves realize about this cunning fox Ali who came all prepare by watching from outside.
