Stargirl Caraway Timeline and Summary

Stargirl starts attending Mica High as a tenth grade student. Before this, she had been homeschooled by her mother.
At school, she wears what she wants and acts how she wants. Oh, and she's friendly to absolutely everyone.
At first everyone just thinks she's strange, but then she gains popularity for her awesome cheerleading.
She agrees to go on Leo and Kevin's show "Hot Seat" at the height of her popularity.
But then, when her enthusiastic cheering (and boy do we mean enthusiastic; she cheers for the opposite team, too) gets her into hot water, the school turns against her.
So when she appears on "Hot Seat," she is verbally attacked by, well, everyone.
Despite her unpopularity, Leo can't resist his feelings for Stargirl, so the two of them strike up a relationship.
They have an awesome time together, until the fact that the whole school is shunning Stargirl (and by extension, Leo) comes between them.
Leo tells her she has to change if she wants them to stay together. Because she loves Leo, Stargirl transforms herself to Susan, a thoroughly average girl.
But her transformation has no effect on the school's treatment of her, so she goes back to being Stargirl. She's cool with how she is, but Leo isn't so happy.
Because Leo won't take her, Stargirl attends the Ocotillo ball by herself, where she has an awesome time and regains her popularity.
That is, until Hillari slaps her, telling Stargirl that she ruins everything.
After that, no one hears from Stargirl again.
