Parvez talks with his friends about this problems...
Look at his eyes - they will tell you everything.
They think, he's taking drugs...why did this happend?

At the same evening.
Huh - why is my son is praying ??!!??
A few days after that, Parvez and Ali are together in a restaurant. Parvez wants to talk with him...
You're not in thevillage now. We have to fit in. This is England!
Another whisky please!
But they hate us!
But its forbidden!!
...but the situation escaleted quickly.
Then why is he letting a woman like you touch him like that?
Your father, who is a good man, is very worried about you...
Later, Parvez and Bettina picked up Ali in front of a mosque. After Alis and Bettinas conversation, Bettina leave the car.
Parvez found Ali in his room and beats him up.
