When Ben Solo was a kid he wanted to be an engineer. Nothing prestigious or daring, as befits his family legacy. Just a tech. Just working with machines and computers and fixing them. Once it was discovered that he was Force sensitive, Ben's humble life goal didn't matter anymore and he was shipped off to train with Luke.

Now, whatever ship Kylo Ren is on, he sneaks off as Matt the radar technician to spend some calming downtime doing what he really enjoys: fixing tech.

Hux finds out.

up to anon how Hux responds/if Hux even knew what Kylo Ren looked like prior to encountering Matt the radar tech
