"I'll tell you one thing," Kevin said as we joined the mob in the hallways, "she better be fake."
I asked him what he meant.
"I mean if she's real, she's in big trouble. How long do you think somebody who's really like that is going to last around here?" (2.25-27).
Kevin clearly believes that someone like Stargirl cannot have an identity like hers and make it in society. Stargirl will either be eaten alive, or she'll have to change into someone less strange, less shocking, and, most importantly, less genuine.
Quote 2
"They're not talking to her."
The words didn't stick. "What do you mean? Who's 'they'?"
He cocked his head at the sea of tables and eaters.
"Them."
"Who them?" I said too unhinged to laugh at my grammar.
He wet his lips. "All of them." He shrugged (18.32-35).
It's the moment of truth for poor Leo. This conversation with Kevin is when he realized he has been banished from Mica High society. The conversation is revealing in other ways, too, because Kevin is showing us the power of "Them." The mysterious collective meant to include all the people out there whose opinions we care about for whatever reason. In this case, it's the high school society that has chosen to shun Stargirl, and by association, Leo. This is the "them" that Leo must decide if he cares about more than Stargirl.
Quote 3
"I want to put her on Hot Seat. Dorko Borlock here doesn't want to (7.48).
Do you think it is okay for best friends to call each other names, even if they are just trying to be "funny"? Kevin just might be confusing humor and general jerkiness. Not a good idea, dude.
