10 Dream Star Trek Moments That Could Still Happen

10. All My Friends Are Dead

800-odd years is already a long life, even for a hologram. First activated on Voyager in 2371, soon to be teaching at the Academy in the 32nd century, the Doctor will not only have lived, he will have seen generations of friends die along the way. And, as Robert Picardo pointed out during Trek Talks 4 this year:

Digital memory is completely clear, which means that a beloved colleague, like Captain Janeway […] [is] as present in his memory, 900 [sic] years on, as when he was working with [her] in the 24th century.

That bittersweet fact leaves us with a few dream possibilities. The Doctor's trips down memory lane could see the on-screen return of any one of his former crewmates. He could chat to B'Elanna aboard Voyager in a daydream, before being interrupted by a student mid-lecture! (More on other legacy characters later.)

An EMH that doesn't age still poses a few technical questions about de-aging. The Doctor can alter his physical parameters as he sees fit, but there needs to be some sort of explanation for the audience. In Star Trek: Picard, Q snapped his fingers. The Doctor can just tap his mobile emitter. The ageing process shouldn't be too much of a stretch for his subroutines!

For the 'Octocentennial Man,' there is also always the possibility of transfer to a synthetic organic android, or 'golem,' body — one capable of ageing. The Doctor might prefer that, in fact, to flickering every five seconds like every other bloody hologram in the future. The end of that really would be a dream come true!
