As most of us know, it wasn't uncommon for characters from one series to make appearances in others. Bashir and Quark did on TNG, Picard and Riker (well, sort of Riker) did on DS9, and Troi and Barclay did on VOY. But Reg never appeared on DS9, and I wish he had. I think it would have been great to see him interact with the crew, especially his former Enterprise shipmates. What do you guys think a DS9 episode with Reg might have been like? What would you have liked to see?
