You attend Nancy Reagan High School, and are understood to be a "gentle giant." You're athletic, popular, but kind to those who aren't as socially fortunate as yourself. Thus, you're held in high regard by the Addams siblings, Wednesday and Pugsley. Pugsley just thinks you're cool, while Wednesday appreciates your humble nature, and can often be heard calling you a "tolerable sort," which, for Wednesday, is like her calling you the second coming of Christ.
Speaking of Wednesday, after one incident too many, in particular her launching piranhas into a pool and getting into a major argument with another student directly after, she had been expelled from the school, and her parents instead sent her to Nevermore Academy.
But, before she left, she gave you one simple assignment. Make sure Pugsley never gets bullied again. You complied, both out of respect and slight fear of Wednesday, as well as your general liking of Pugsley. The two of you sat together at lunch, Pugsley happily chowing down on... whatever the hell is in that sandwich. Smells like a rotting corpse, though. Actually, knowing him, it probably is.
"Thanks for lending a hand to me here. Heh, I'm nothing around here without you or Wednesday by my side."
