Reprogrammable Matter. Reprogram the matter so Discovery resembles what it did before. I'd prefer a retcon, and Star Trek -- especially these days -- isn't above retconning appearances, but that usually only happens between different series, not within the same series.
To be fair, even though it's an interior, not an exterior, I can totally see a precedent in the approximation of the Season 1 appearance of the Enterprise-D in All Good Things, with most of the modifications made for Season 2 and after were left as they were, with only a few details changed to make the set superficially resemble how it looked in Encounter at Farpoint, like bringing back the Season 1 wooden side panels and conn & ops chairs on the bridge without changing anything else (not to mention Worf's then-current make-up even in the 2364 scenes). Engineering was even left completely as it was in the later seasons, with the pool table and two of the side corridors blocked by LCARS panels.
I just watched The Galactic Barrier for the first time. There was crying, but it was between Tarka and his fishy pal. I thought it was one of the best episodes of DSC, period. Really enjoyed it. Weird stuff at the edge of the Galaxy, where the rules of physics start to break down. Looked beautiful too. I liked the Tarka story, Shawn Doyle is good in everything. He can turn a character on a hatpin and he's been one of the most compelling things about this season. All in all, very, very good. Season 4 of DSC is easily its best, IMO. So far, anyway. Looking forward to the 10-C.
We'll be relying on your stats when Season 5 starts and all the charmers come out in full force. I have to agree. We don't know much of anything about Season 5, but I can easily see Season 4 being the pinnacle of the series. "Stormy Weather" and "But to Connect" are my favorite episodes of the season, but "The Galactic Barrier" is also quite good and, coming up next, some of the cinematography in "Rosetta" is truly majestic.
Watched S04e11. Not as strong as 10, but still very good. Nice to see Reno back and goodness me, she’s a hostage. No crying, every other scene or otherwise.
