Corrected entry: When the two guys steal the guns from the manor house the character calls the other "Kenny". Then the part where his hair gets shot he then starts to call him "Gary". This continues within the next scene.

Correction: Right before the scouse robbers enter the house, one of them (Dean) says to the other (Gary) "Let's call each other Kenny, all right Gary?" It's not a character mistake, they're just using fake names to keep their identities a secret.
