{Olive Daphne Doyle}
Really, if she hates high school so much, she should probably just quit.
But she knows she can't do that.
She needs the knowledge the feeling of contentment.
In elementary school she was the weird smart girl.
Here, she has a guy in love with her (though she wishes he could stop), a best friend, a whatever-Fletcher-is.
If she quits, she'll be back to a normal school, with normal kids, and she isn't normal.
But she wants to get out of this tortuous place
So she pretends.
(Plays with the whole memory loss thing; maybe it's easier being stupid than being a genius}
In the end, she stays in the very place she wanted to escape
She says she's happy.
She is.
...
{Chyna Parks}
She's sorry she ever left her ant pad out of her sight.
That makes it kind of her fault.
At least, she thinks it does, that her best friend in the world is like this.
So when she finds out that Olive was faking, obviously she's angry.
Who wouldn't be?
All it takes to forgive her is a remembered speech, really.
That's what best friends do.
Besides, who else could she have sleepovers with?
...
{Fletcher Pumpernickel Quimby}
He doesn't show any remorse for plugging the amplifier in, really.
It's actually a good thing for him, right?
Chyna not having a best friend around, turning to him for companionship, it's his dream.
No Olive around to mess it up.
"Chyna misses you" he says, and so it's true.
(He tries to ignore his "yeah she's back," that's the tiny part of him who used to have a different best friend escaping.)
...
{Angus Chestnut}
Still rejected even without her memory?
He wishes he were surprised.
But he isn't. By then, he wants his Olive back.
Because, for some reason, he's in love with her, and this girl isn't her, even though she looks like it.
...
{All}
After the dog situation is cleared up, they all cit around and drink the grape juice they made.
Well, all of them except Fletcher, as he's been perpetually grossed out.
