his second name is "Altan"

he committed his first perfect crime at 7, burning down the local police station with an iceball soaked in gasoline, after they'd beaten up his father. they never found out who did it

it took him a full year to call himself "Day" after the Trial. the full phrase is "Because every day is a new 24 hours. Every day means everything is possible again."

his first kiss was at 12, by an older girl who'd caught him stealing food and instead of ratting him out called him "cute as a goddy button" and demanded that as a payment

the wound at his knee (from the Trial, before he got the artificial one) didn't heal for a good 3 years

his older brother, John, did eventually find out he was still alive bc Day got hurt very badly and didn't knew who else to turn to. he kept the secret and Day would slip him food, money, whatever he could spare at times

he could only bear to stay away from his home for one month after the Trial, then he was back to watch from afar and check in on them at least once a week. he regularly picked flowers for his mum to leave under the porch (unseen by anyone but himself)

the pendant he always wears is an old USA coin, encased in metal to be unrecognizable. forbidden to own, but his father brought it from his work at the front and reasoned no patrol would closely check a childs trinket

his family never had a pet, but they tried very hard to keep some plants alive

at the gas station the first (and yet only) plushie he picked out is a little arctic fox

he once "got lost" in a restricted area of his schools library, looking for history texts

the official score he got on the Trial is 674 (of 1500, 1000 needed to pass) - it's what tipped June off something was wrong, bc that is suspicious low

he loves peaches
