Here is his original design!
Because of the fact he has gotten used to being alone, he can be a little awkward and doesn't always take part of other boys' conversations and games. However, he isn't sad about it and others understand it, even though they do try to drag him with them anyway. Jet is usually seen carrying a book or even two - an old habit he developed as younger.
Despite seeming distant, Jet is actually very good at noticing how other people feel and in general he is very feeling oriented individual. He also has an incredibly good face memory, and he can usually remember where he saw someone and when, and what they looked like. As such he is also very good with small details, and many find this talent of Jet's very charming once they get to know him. He is definitely the most mature and responsible out of the boy group, but unfortunately he isn't very good with words or doesn't always know how to take action, so his good intentions are sometimes eaten away by his own other insecurities. He can sometimes be a little group confirming too as he doesn't really want any more trouble than he already has because of his scars.
He is much, much warmer and kinder than I initially thought he would be like. I think in a way you could say that the qualities I originally took from Leon went to Jet. That's why those two really balance out each other and make a very good duo.
In the very first prototype of Sinfonia, Jet was actually a boy named Michel. He was a tall and silent boy with incredible physical powers, and he was Rick's best friend of sort. I guess the idea of a super small first grader and super big and tall third grader was really appealing, but in the end I scrapped that idea because Michel just didn't resonate with me enough. He was too much of a trope and didn't feel like a person, and once I designed Jet I immediately knew he would take Michel's place. And I honestly think that's way better, because the personalities of all the boys really complete each other right now as they are.
I don't have much more to really talk about his development as I don't have more art of him tbh but here are some really good Jet trivia:
- Leon convinced Rick that Jet really is the next heir to a gangster family and Jet actually played along with this, resulting in Rick believing it for a week until he realized he had been fooled. Rick was angry like 3 hours. He tried to be angry for the entire day but Rick can't stay angry for long.
- Jet got Leon into reading during his first year. He gave Leon some books during the summer so he would have something to do during the boring moments, and Leon actually tried and liked them.
- Speaking of those two, Jet and Leon sometimes spar together, and they are pretty good team fighters too.
- Jet's mother is mute and he knows sign language!
- Sometimes during rainy days when nobody is seeing, Jet helps out worms to cross roads so they won't get squished... He feels really sorry for the worms
- He received the scars from the Lucien of his world. I can only fear at the mental image of human Lucien. I wonder what happened after the incident?
- I like to think Jonathan feels the closest to Jet somehow out of all the boys in the group? It's probably the fact they are both on the calmer side and definitely more responsible than Leon, Rick and Walter are most of the time.
