I really enjoy this change
In the comic, Cecil brings mark into the white room for the entire discussion, showing he was planning to subdue mark the entire time
In the show, Cecil has his discussion with mark while walking, and asks mark to “please go” multiple times. Contrasting the comic book where Cecil is more of an asshole and had planned this from the beginning. He also stops outside the white room and signs showing us he’s not to happy with what he might have to do
