SPoiler alert! (about viktor's dad)
In the scene where he gut-shoots the boss Traffikant, is it a lighter that he hands him ?
And if yes, is it an analogy with the lighter Viktor 's mom finds within the envelope full of cash way earlier in the movie... meaning that he somewhat takes revenge for the fact Traffikant sort of switched his already bad father for an even worst 1 (the mentor that ends up trying to kill him )? (isn't that a cheerful movie :)
