My thoughts:
* I'm surprised that the fact that Covich (David Cronenberg) and Georgiou's conversation about Terran-Vulcan First Contact was a direct reference to In a Mirror Darkly, Part 1's teaser, which depicted that very event, hasn't been part of the discussions on the episode that I've seen
* I'm 99.9% positive that Nhan will be back before the end of the season
* I get Admiral Vance's caution, but he didn't need to be such a dick at the start of the episode
* I hadn't made a connection between the 'shared melody' plot thread introduced here and the 'All Along the Watchtower' plot from BSG until it was brought up on every single DSC podcast I listen to, but I think it's neat that a show that was intentionally designed to be as antithetical to Star Trek as possible has ended up influencing Star Trek at least in part
* Why didn't Saru press harder for news about Kaminar?
* I don't think Vance is going to part with Willa even though I've seen some speculation that she'll join the Discovery's crew; however, I wouldn't be surprised if we do see a 31st Century Starfleet officer assigned to the ship
* I'd be very surprised if Covich and whatever he did to Georgiou isn't connected to Michelle Yeoh's starring role in the Section 31 series
* Willa's reaction to the Mycelium Gang's functional disfunction was great. I do think Jett was just disagreeing to prove Stamets' point rather than actually disagreeing with him, though, which is new
Wasn't the ENT "footage" MU Vulcans arriving on MU Earth? I inferred Kovich was talking about MU Terrans meeting "teh Prime" Vulcans during the first crossover. But you have a point that it seems to be the example from ENT.
IMDB currently doesn't list Nhan for any other episodes this season. But didn't we see some images that showed an aged Nhan?
