He is described as a 17 years boy. His personality changes throughout the story from in the beginning he is a kind, funny teenager but later after Seattle's father shows up he becomes mean only because he was trying to protect Sea.
Symbolism: "I held the new skateboard across my chest like a shield" (238)
There isn't a true antagonist in this novel but if there had to be one it would probably be Sea's father Frank because he is the character that ends up changing the story from being good to bad.
Foreshadowing: "I've been meaning to tell you something."
The theme of this novel is to always believe in your family. This is the theme because when things started to fall apart when Seattle's father appeared, in the end, they came back together as a family and things turned out alright.
Imagery: "I flicked the shaver on and felt it vibrate in my hand ... Fifteen minutes later I buzzed off the last bits of his bleach blond hair. Now Critter looked more like a marine recruit than the womanizing crooner he'd admired since he was seven." (242)
Whenever Seattle is riding her skateboard she is just happy. The skateboard symbolizes just plain old happiness. When her father showed up she went running looking for her skateboard but it was at Scott's.
This is foreshadowing Critter's and Sarah's break up. She was still with her ex-boyfriend while she was seeing Critter. Critter gets sad and depressed.
This created good imagery because it gave a good image of what Critter looked like after Sea shaved it off. The relation to a marine recruit gave a really good image.
