10 Crazy Star Trek: Picard Season 3 Theories
8. Please State The Nature Of The Medical Emergency
He's a doctor, not a detective!
To be perfectly honest, this whole theory, rational as it may be, centres around one thing: we here at TrekCulture have a soft spot for The Doctor from Voyager (maybe he's gone with Joe again? Shmullus?) and want to see him back.
We know that in order for Holmes and the crew of the Enterprise-D's archnemesis Moriarty to be able to get around, he's probably going to need the help of a certain mobile device for those hard to reach, no holo-emitter places. As it stands, there is only one 'autonomous self-sustaining mobile holo-emitter' known to exist in Starfleet and the Federation – and that belongs to Voyager's EMH. Could The Doctor be making an appearance in order to hand it over to Moriarty, therefore? He did lend it to holo-Barclay for a while aboard Voyager in the season seven episode Inside Man, but that got ugly fast.
The technology was widely available in the alternate timeline of Picard season two's episode Hide and Seek – Emergency Combat Hologram Elnor can be seen wearing a mobile emitter, in fact. Towards the end of the Star Trek: Voyager episode Renaissance Man, The Doctor did speak about donating his emitter to the Daystrom Institute (albeit when he thought he was about to decompile) in the hopes that they could replicate it one day. Perhaps he lent it to them for a while when Voyager got home and now all holograms are fully footloose and fancy free in the 25th century.
Of course, The Doctor doesn't have to be present to donate his emitter for the good cause. He could just give it to Seven somewhere off-screen. We REALLY want to see The Doc in the flesh though, or, rather, in the photons and forcefields! This feels like the perfect opportunity for one hell of a cameo.
