Badge tap, badge tap, Data does it, Picard does it. And so they should, some would say, but others would refer you to the Technical Manual, wherein it states (so I'm told, I've not read it) that badge tapping is not necessary on board the Enterprise. Perhaps Data does it to pretend that he's human after he sees the others doing it.
One or two quibbles. Q refers to himself as omnipotent at one point. How then can he have superiors? What are they, more omnipotent?
When Beverly is tending to Data in sickbay and tells everyone to leave, Picard orders a guy to stay with Q. A scene or two later, the guy has disappeared, and Q is striding around the ship completely alone. What happened to the guy who was supposed to keep an eye on him?
Q asks of Data "What are you looking at?" and Data replies "I was considering the possibility that you were telling the truth." Which would make sense in the context only if Data were human. We humans are aware that the query "What are you looking at?" may well actually mean "Why are you staring at me that way and what are you wondering about?" but this, excuse me, is Data the Literal Boy we're talking about here. This response seems a little out of character for him, doesn't it?
