I am going to be 100% honest and say that it's neither. It was me thinking his name was David and missing some parts when I went back and edited. Thank you for commenting, since I wouldn't have caught those leftover misnomers without it! Hopefully after going back a few more times and changing the ones I've missed, it's all cleared up!
Oh! I'm a dumbass, lol! I read you creating a tag for him as intention for 'David' to be an original character. VC is a micro fandom that's always thirsty for new writers, so thanks for posting the fic, and I hope you'll be inspired to write more!
