"Why don't you do it?" Alan responded. "I did say it would give you a chance to bond with your sister, so why not?" And a moment later, he added, "And I can handle the babysitting, so you don't have to worry about that."
Jeff shrugged. "Well, alright then. Just don't let the power get to your head." He turned back to the Chronivac, his profile still open. "Shouldn't be too hard, just have to..." Jeff moved to the age field, erasing the 16 and putting Lucy's age, 9, in its place, then setting it to shift reality, so Lucy wouldn't see anything off. "There. Now all that's left is to confirm."
The boy scrolled down to the confirm button, but then stopped himself, a thought coming to his head. "Actually, before I do this... Should I turn myself into a girl, too?" He asked. "Don't know how they'd feel about a boy joining an all girls sleepover, especially with one already babysitting."
