When you're angry Peter does whatever he can to extract you from the person or thing making you angry.
You have two modes when it comes to anger, Dry Anger is when you are so angry that you are just cold, closed off and bitchy. Wet Anger is when you have too many emotions built into your anger and you are hurting.
he'll take you to a secluded place if you're dry angry and he'll get you to calm down. When you're in this mode, you do not want to be touched, talked to or anything. You want to punch something. So he takes you to where he has a punching bag and lets you have at it.
When you're in the Wet Anger mode, he gets you back to the treehouse and into pajamas. He then holds you while music plays or you're crying or ranting. He cancels the rest of the day for you to recover.
Very late update but i just typed this up, when i do these "when you're..." chapters that means I did not have something to go up and I actually had time to sit down and write something.
So sorry this sucks but I got something up :)
