!!Tropes in this episode:

* AmbiguousGenderIdentity: Adira Tal formally follows up on the show's promotional materials saying they're non-binary, shifting to "they/them" pronouns. The crew, in grand ''Star Trek'' tradition, accept it without comment.
* ALighterShadeOfGrey: Much of the initial conflict of the episode comes from this. From Book's point of view, the situation is a CainAndAbel scenario, as his brother Kyheem sold out to the Emerald Chain and supported selling them the planet's trance worms and knuckling under to them in general. Kyheem sees it as a FoolishSiblingResponsibleSibling one, as Book left Kwejian years ago, cut all ties. The episode generally shows Book as being more sympathetic.

* BrickJoke: At the beginning of the episode, we learn that Linus is not allowed in the mess hall until his shedding cycle has ended. At the end, Burnham introduces Kyheem's son to Linus and says he can take off part of the saurian's face if he likes.

* LoopholeAbuse: To stop Osyraa, Tilly suggests Detmer go on an "unsanctioned" mission to disable her ship using Book's ship, rather than having a Federation vessel attack her directly and risk starting a war between the two powers. Detmer pulls it off, but Osyraa sees through the ruse and promises retaliation.

** The Burn has a discrete origin point.
** The lullaby from "Die Trying" is a distorted Federation distress signal that comes from aforementioned source, which is still transmitting on a loop.

* SnarkToSnarkCombat: Georgiou and Culber share a particularly hostile back-and-forth snark session on the subject of her deteriorating condition, because she's too proud to admit to any weakness and he knows her well enough to know that she won't acquiesce unless he can give as good as he gets.

* TookALevelInJerkass: Okay, Georgiou's always been an evil jerk, which is SOP for Terrans, but she's even nastier to Culber than usual because her pride won't let her show weakness even though Culber has her number on that subject.

* RealityEnsues: Osyraa is not fooled for a second by the pretense of having Detmer attack in Book's ship and declares war on the entire Federation regardless.

* {{Transgender}}: Adira Tal formally follows up on the show's promotional materials saying they're non-binary, shifting to "they/them" pronouns. The crew, in grand ''Star Trek'' tradition, accept it without comment.

* OrbitalBombardment: Osyraa starts firing upon Kwejian's shield when Kyheem won't give Book up. Detmer manages to disable her vessel before her attacks can overwhelm the grid.

* ALighterShadeOfGrey: Much of the initial conflict of the episode comes from this. From Book's point of view, the situation is a CainAndAbel scenario, as his brother Kyheem sold out to the Emerald Chain and supported selling them the planet's trance worms and knuckling under to them in general. Kyheem sees it as a FoolishSiblingResponsibleSibling one, as Book left Kwejian years ago, cut all ties, and hasn't helped them one way or another since then. The episode generally shows Book as being more sympathetic.

* CatchPhrase: Saru is working on his own catch phrase for spore-jumping and giving other orders. "Manifest" is dropped immediately. Trying Pike's ("Hit it") falls flat, especially when Saru tries to put his own inflection on it. "Execute" doesn't do much better. "Carry on" earns a mild shrug.

'''Georgiou''': What you need is not imp(zzzzzzzzz)\\
