Wait i can’t remember who is the white haired man ?? Can someone tell me who is he ?

His son was the one who betrayed them

So basically the white haired guy was the father who betrayed them ? Is that right ?

* I mean the white haired guy was the father of the boy who betrayed them ?

NO! The white haired prick is Lucas's big brother, not father. And yes he is brother of that prick who betrayed them.

Oh, oops

Ohh ok! Now i get it thanks to you!
