Yes! I have that he worked on Scheria a number of years back, various jobs, so he could have done security for one of the labs for sure. Or maintain type mechanical work. Either or. So they could have worked in the same place and hit it off in the lunch room or some such, and then kept in touch when whoever left first left! Perfect. I'll have him send Fletch a message to open up the convo for when he's back on the station!
