1: Sometimes she wonders if Sherry and Roxie aren't an alternate universe Kumi and Kasumi
2: Her relationship with Red Snout has gone exactly back to how it was before, only now it's worse because Red Snout's terrifying her in order to "toughen her up". Nothing is worse than someone who thinks they have a good motivation.
3: She may seem rather immature in comparison to the other girls her age. This is a semiconscious choice by her. Ever since she joined the Alien Party, she was forced into trying to be more grownup, at an artificial pace. Saying "no, i'm a human kid and this is the rate human kids grow up" is an act of rebellion.
4: She's unsure of her feelings about being "the sweet one" of the group. Yeah it's nice to have people like you, but she wonders if it's preventing people from seeing how great Roxie and (to a lesser extent) Sherry and Vega are.
5: Cowardly in face of personal danger, she will rollerblade into hell itself to protect her friends.
6: She's more used to aliens and other gross things than most kids. A little more than Sherry at this point.
7: She has her suspicions about the real purpose of the Alien Party but has no way to investigate. Borg ain't talking.
8: Yeah, she has big ears.
9: Is not, and never will be, someone who blooms into grace. Come puberty, she will be just as awkward, but taller.
10: Due to events of her canon mirroring those of magical girl and -mons shows, has become dangerously genre savvy. That doesn't stop her from getting her image of romance from shoujo manga.
11: ...Which, when combined with her enjoyment of playing matchmaker, tends to result in things like triplines to force people to trip into each other
