In the Godfather, when the Corleone family plans to kill Sollozzo and McCluskey, Michael receives the instructions, from Clemenza:
Then when you come back, you come out blasting... And don't take any chances. Two shots in the head a piece.
However, when he comes out of the toilet, he sits back and keeps on talking with Sollozzo, in italian, so here is the translation :
SOLLOZZO: You're OK?
SOLLOZZO: I want you to understand something. You're Italian like your father. Your father is not well, and when he's better, we'll need your help. This war has to end. You need to help me to end this...
I'm not sure I understand why did he wait. Was he scared of shooting at someone? He was a marine that fought in WWII so he might have experience in killing and not be uncomfortable.
Was he trying to get some more information from Sollozzo? I'm not sure of that too, because when he comes back from the toilet, Sollozzo don't say nothing important (maybe I'm wrong) before being killed.
Any additional information from the book would also be welcome.
