To be honest, this one felt a bit lopsided. The A-plot with Hunhau felt very formulaic and predictable, and the episode's most valuable moments came from the interspersed character moments and finally, the consequences of Burnham's unauthorized mission. Right at the beginning, where Burnham said "yes, Sir" to Saru after he ordered her to stay, it was obvious she was going, even before she asked Georgiou for help. It felt a bit like a late-season Game of Thrones episode where the writers knew they had to get Book back on the ship and Burnham reinstated as a science officer, but the execution ultimately fell flat. Nevertheless, having Georgiou taking the reins served the story very well, and she seemed to be pretty much in her element outside the Kovich-induced flashbacks that kept incapacitating her. I just hope it's not some stupid "look, we cured your evil" thing.
Once again, we're in a situation where both sides have a point. Michael's timing, however, is still dead wrong as she once again made a highly emotional decision. She could've just waited for twelve hours (it wouldn't have changed Book's situation a bit) and then request a personal leave when there wasn't any urgency. Sisko was quite lenient in letting various crew members do just that, after all, and it's no surprise she was sternly reprimanded, something way overdue since her dangerous gamble in
People of Earth. Vance was very reasonable in letting Saru handle the matter and made some good points about her getting valuable intel and freeing slaves, which is probably the only reason why she wasn't demoted too.
I was glad that they placed so much focus on Saru distrusting Burnham after what she did. This whole arc felt quite like the old "why do they treat Ripper like a pack animal?" or "why did they make Spock a murderer?" fiascoes from the previous seasons. We really need to stop treating every single plotline left hanging as a plot hole just because they didn't resolve it within one episode. This isn't the Berman era anymore.
One of the biggest surprises for me was Saru's scene with Tilly, actually. Her advice to him about going straight to Vance firmly set her in her position as the emotional heart of the crew. Michael might be one of the people she loves most in the entire universe (that's probably as good as it gets... I need more Mylvia content, dammit!), but she has to look out for all of her friends and wants the best for the entire crew and right now that depends on Future Starfleet trusting them. That's Captain Tilly for ya. And of course I enormously enjoyed Saru being so angry at Burnham that he didn't even scold Tilly for saying "Oh shit," and actually concurred instead.
Speaking of Tilly, her scene with Grudge was absolutely lovely, I grinned like an idiot throughout, right from her freezing in the door with a face that said "why is my room meowing?". As someone who's had four cats in his childhood home, I know exactly how annoying it is when they lie under the bed and just refuse to leave. And of course the whole idea of Burnham just leaving Grudge with her without a word... instant funny, I loved it. We finally had some real quality cat content today, especially with Grudge hailing Discovery

Observations:
- If it weren't for the Orions, one could be forgiven for thinking this was something straight out of DS9. The junkyard had definite Cardassian vibes with the various smelters reminiscent of Terok Nor. Also, the perimeter fence reminded me of the POW camp on Cardassia IV from Homecoming.
- Linus, oh Linus. He was a cheap but highly rewarding source of laughs throughout the episode with his constant transporter accidents. I especially loved how Stamets wasn't even surprised, just annoyed. And of course the rules of comedy demanded he'd ruin the big romantic moment at the end.
- Some glorious one-liners this week. "You had me at unsanctioned mission.", "Your emotional spectrum runs from cranky to homicidal.", "I didn't love here" (oops), and of course Stamets' self-aggrandizing "Including me, and I've imagined more than most" at the end.
- I also liked Stamets' mini-plot with Adira a lot, especially how understanding he was about Gray sticking around, and Hugh pointing it out that he sees himself in Adira.
