You'll often see people 'handed stuff', and sometimes, people just off camera. It's likely just a good rule in general to keep ANY baseliners off camera. The most common would be slaves, prisoners, or security, that a capsuleer would keep around their person, in my head anyway. People that that particular character would simply consider 'living extras' to themselves. The Summit is a Capsuleer's space though, not a place to hold court.
As it is, people seeing 'other people' on someone else's feed causes a reaction. Seen it several times. Sometimes its funn, cooll, moving RP. The seeing slaves one prolly got annoingly tedious cause of course, people then wanna go rescue them, and the person with the slaves is possibly OOC going 'no, fuck you' and so there you go.
