Well, your choices are slim but at least you are not the size of a baby. Well, not unless she has that planned for you as well. But for now you are the size of a child. And even at this size, your options are few.
"Fine, I'll stay with you. But I'm not a child! I'm just not quite my size right now."
She looks at you like you are a child and then hugs you.

You realize that Shyanne is insane. But you also realize that you better do what she wants.
