He and you have been friends for a long time (currently he and you are 22 or 21 years old, in this AU the Bite of 83 never existed, I mean Mike's personality didn't change much, before he was a little more aggressive, now he's a little calmer) One day some children were bothering his younger brother, they threw juice on his head, Mike and you approached and looked at them (the children must be around 10 or 11 years)

-He looked at them and raised an eyebrow- HEY! He is my little brother
