1. This summer marks Max's 20th year of existence. Emotionally, he is probably closer to 20 than 42 (Brian's age).
2. He likes to refer to his victims as a group, giving them cute names that refer to them in the collective. The names have been, in order: - The Lonely One - The Darling Duo - The Funny Three - The Fabulous Four - The Golden Five - The Slick Six - The Lovely Seven - The Awesome Eight
3. He's gone on a "date" once. It ended with him walking out in the middle of it because he had gotten bored.
4. Max doesn't have the best memory for faces. He remembers facial expressions more than the faces themselves, and even then, it's often vague. The impressions people leave on him are stronger than their pictures.
5. The night that he beat Hannah up, he pulled a bit of hair from her head and wound it around the button of Brian's jacket. Gloria found it two days later, which lead directly to the confrontation that would ultimately dissolve her marriage with Brian.
6. He loves the sound of his own voice, which is a hair bit more nasally than Brian's.
7. More than anything, he wants to be able to live autonomously.
8. He doesn't dream.
9. The angrier he gets, the more he laughs.
10. Though he exists to protect Brian, one of his greatest fears is that one day he'll no longer be necessary and Brian's brain will destroy him.
