what factors contribute to the bond between junior and rowdy? what part do comic books play in rowdys life?

Rowdy is Arnold's best friend but he also pushes Arnold around. Their friendship is a paradox of sorts. Sometimes Rowdy's only way of releasing tension and communicating is violence so sometimes, like in an abusive relationship, Arnold gets hurt,

I was the kind of idiot that got punched hard in the face by his best friend.

Bang! Rowdy punched me.

Bang! I hit the ground.

Bang! My nose bled like a firework.
