Little spy

Yuzu had felt off all day, like she had a fever, had over eaten, and water in her ears all at once. She didn't want to worry anyone so she went to hide in her room just saying she hadn't slept enough the night before.

But slowly, over the course of an hour, it cleared up, and with it came clarity.

"I can do anything. I can make anything true. I'm...part of everything..."

It was insane, Yuzu understood that. But that didn't make her any less certain of it. Like seeing something that shouldn't be there but was. Still Yuzu wasn't dumb, she took a while to check it out, she conjured a drink and some snacks, she set some parameters so she didn't have to check every word every time. Everything work and was set to her liking.

So what should she do first? How should she first use (****) her new godlike power?

Spy on her brother of course! "This mirror can show me whoever I want when say who." The mirror shimmered. "Good, now show me big brother!"
