Re:
Calypso’s place in the timeline relative to now, and whether or not it’s been abandoned/ignored/retconned, from
an interview with Michelle Paradise at Inverse while they were filming the first part of Season 4, back last January when Season 3 had just finished airing.
Michelle Paradise said:
Calypso has now become part of our canon, and it takes place far beyond our time now even, in Season Three. And yeah, eventually we’ll have to find our way there. So that short, in the grand scheme of things, fits together as a piece. In certainly in Season Three, we were beginning that process with Zora — who isn’t quite the Zora we saw in Calypso — but we were getting that process started a little bit of her sparking to life in episode Four, and then coming in and having a bit more of a presence in Twelve and Thirteen. So, we’re starting our way there.
Around the same time Alex Kurtzman and series director Olatunde Osunsanmi were
interviewed for the Blerd Gurl Podcast where Kurtzman spoke about connecting the show to
Calypso as well.
Alex Kurtzman said:
We definitely knew that we wanted to connect Calypso to Discovery. And, obviously, we did because we did it in Calypso. Calypso ends with a big open mystery, which is: how did how did this voice end up on the ship and why is the ship empty? So we have a lot to answer there. We love connecting Discovery to the trek to the Short Treks.
Given that since the start of the new season, with the Sphere Data/Discovery Computer calling itself Zora, they’ve further connected themselves to
Calypso, I don’t think there’s any indication it’s been retconned.
And as to the discrepency between the pre upgrade look of the Discovery in
Calypso and its current status, currently my best guess/explanation is it reverted back, at least in appearance, by utilizing programmable matter.
