Mia here, back with pup number 2 because I couldn't resist.
This is Josiah. For the Bible inclined, he was named after one of the twelve righteous kings of Judah. And while his namesake did a lot of good things what with going to war with Egypt, becoming king at the age of 8 and fathering four sons (not at the age of 8), this Josiah scores lower on the list of achievements.
He is an orphan and has been raised in the spirit of the Catholic faith since he was found as a toddler. As a result, he is good with following rules, obeying scripture and the nuns and bad with everything else that shapes a normal existence. Your character probably knows him as the weird robotic kid who speaks nonsense and sometimes to himself. Depending on whether your characters have a good memory, they might also recall seeing him walking in their dreams. He tends to be more talkative in there.
I'd love lines with everyone. Tormentors, friends, weirdly interested fellow students and faculty all welcome! You can poke me at kimchi rookie if you feel like plotting.
