I live in Virginia, maybe 30 minutes from Roanoke. I asked my buddies about him, and apparently people see him around town all the time, so I know he's lived in my city for quite a while. I didn't hear them say anything interesting, they were just grocery shopping. Nothing out of the ordinary. I didn't want to bother them so I recorded quickly then went on with my day. But if I see him again I'll keep you all updated if things change!
I will say the only thing that really struck me as odd about them was that they kept looking around nervously, as if they were scared someone would recognize them or try to interact with them. You can even see in the video the lady kept glaring at me even though I had only been in their aisle for less than a minute.
