Season 3 did have one of my favourite lines though

Miguel: I accept you. I accept you, Dexter, like a brother!

Dexter: I killed my brother... I killed yours as well

Yeah this was my thought, all Banksy needs to do is design the stencil and then he can get anyone to go paint it on a wall he wants it on

Not saying that is the case here but its fun to think how he might get things done
