absolutely! s/he would ideally be an established independent investigator based on terminus (although whether they have jobs that take them off the station would be completely up to you!). selina here is a former peacekeeper who's been a security officer aboard the endeavor for most of the year and has a lot of downtime when the ship is docked. she misses her job as a peacekeeper and so she's going to be recently hired on to help the pi, mostly with research based stuff to free up the pi to have more time to be out in the field so to speak. additional lines would be that they would be helping ~solve investigate her brother's murder and ~pin is wanting to get into investigating so they would be a potential mentor of sorts - you'd have to speak to each of those players to hash out all the details there (which i can point them to this post if you're interested)! also, there's some t-sec officers in game they could potentially work or clash with depending on what you might have in mind for them.
