You've got free reign to make up whatever you feel suits him! The hacking/programming knowledge and working with Jayden were the only things set stone!

If you'd like, he could have done some serious damage to files/systems in the station as a middle finger to the producers while he was getting caught. That's an established thing that happened.

If you want to know about specific bits of culture/life on the stations. the info docs linked in this comment have some basics and I'm happy to ramble about anything else that you'd like to know. Just give me a topic to talk about!
