Jonah is Vi’s personal mechanic and first contact outside of her duties. While initially being dismissive of her and just wanting to do his job, he quickly began warming up to Vi (much to her chagrin) and began trying to open up Vi’s prickly personality. He's also her overseer and has been put in charge of making sure she follows missions while not actively under orders.

Jonah is an extrovert in an introvert’s body. He has an immense anxiety about talking to people, but once he establishes that link he quickly opens up as a high energy person who could talk about anything from the current climate to a spec of dirt for hours. His entire life Jonah’s loved machinery and how it works, so when he was hired to be an Angel mechanic, he was ecstatic. But he’d quickly learn he’d find more than he thought he would.

However, despite being told to see Vi as nothing more than a glorified computer, Jonah would quickly want more than just a job with Vi. He began talking to talk with Vi, and would realize there was far more to her than even he expected. Mainly, she was once human. All Angels were. She did not know of her past, but knew she was a human at one point.

The two would begin to grow close to each other, confiding in the others about their issues with their lives and exchanging cultures of humans and Angels. Now they’re close friends who rely on the other to get through the days, each looking forward to the other’s small company after VI’s deployment is completed.
