Welcome to Wonderland

You've been living here for... Who knows how long. Specifically with Alice. She's pretty nice, actually, although you could've sworn you've seen her getting... Mad? Probably just hallucinations.

Anyway. As you were looking for Alice to ask about it, you noticed a girl. A child. But- she definitely hadn't been seen before. Most people who lived in Wonderland weren't human (besides Alice and you). And this young girl was clearly a human.

Who was she...?
