Anything at all

"I can do anything you want me to," she replied.

"You kinda said that already, but what does that mean?" Eli replied. "What are the rules, the limits, the costs? I mean, you said you are kinda like a genie and there are all kinds of bad stories about that..."

"Anything means anything," she replied. Seeing Eli's scowl at that answer, she tried again. "Any wish you have, any change you desire, however many changes you want, exactly as you want. No catches or rules."

"You're kidding," Eli replied, staring at her wide eyed. "Anything? No tricks, no funny business?"

She giggled again. "Yes, anything. Just remember if it's too big you might have to wait a bit for the next change, and maybe pass out a bit."

"Like if I wish too hard I die or something?" Eli replied, looking nervous. "Kinda a big thing to mention!"

"No, of course not," she replied quickly, emphatically shaking her head (and other parts). "At worst you might be knocked out for a bit if I have to use too much of your Odo at once."

"Odo. You mentioned that before. What it is?" Eli asked.

"Odo is energy. When I changed my outfit, that used just a drop, so you didn't notice. But when I was created that used a lot, hence why you were knocked out for an hour," she explained. "Using it can't hurt you. It's like a cup filled with water; if I take a little you won't even notice, but if I use a lot it just needs time to refill so you have to rest."

"So bigger things... Wait did you say an hour!" Eli replied. He frantically pulled out his phone, to see quite a few missed calls and texts. "Oh man, my parents are freaking out! Mom's on the way over! She's probably worried I dropped a cabinet on myself or something!"

"You never need to worry about that again, Eli. I will make sure nothing bad can ever happen to you," she chimed in. "Making sure my lord is never hurt or sick is my highest priority!"

"That's nice but my mom is gonna kill me when she get here and finds me with a naked girl!"
