So, I wanted to make Michael able to shrink because of the experiment, but I can't 'cause William already has that ability, he doesn't use it because he think it's embarrassing and he doesn't find the need to use it, so yeah. And for Cc, and his eyes, if you don't Understand:
Well, when Cc died, he knew it wasn't supposed to happen because even though Michael bullied him, he never hurt him physically, and he protected him sometimes, so he forgave him, and that bond a love between them so strong that Cc can locate him with his eyes, the pupils will change for what happen, when he search for him, when he doesn't find him, when he find him, when he retry to find him etc.. I will explain another time with examples and more details, but you'll have to wait, if you want more informations, you can ask me in the comments! enjoy!
