Rey won't be affected, since trying to define a "childhood" for her would be too damned confusing. Which means she can be the reluctant babysitter for kids everywhere! (Also there are tons of places to sneak and hide at her Speakeasy and its cellar.)

I'm kinda waffling on Ravine (whip_poor_will), though. On one hand, she doesn't sleep, but on the other - this event could make an exception out of that, because it's tempting to play around with the memory of her living self. It would be before her people were deported to Babylon as slaves, so she'd be Yehudit, the little 9-year old psychic girl from ancient Jerusalem waiting for her baby brother to be born. Her psychic abilities would be watered down a lot because it would be before they developed as an adult and amplified when she became a reaper, so while she might know things about characters that they haven't told her, it won't be anything crazy. She also has less of a filter when a child than she is as an adult/dead person, so while Ravine would normally keep the stuff she sees to herself, Yehudit would be more gabby and blurt shit that she probably shouldn't. Rude as heck.
