Murphy lights a fire that sparks calamitous events in Shallow Valley. The widening schisms forming in Wonkru worsen and may become permanent.
Tropes present in this episode:
- Armor-Piercing Slap: Clarke wordlessly slaps Bellamy after Madi's ascension.
- The Chessmaster: Murphy effectively orchestrates the entire riot between the Eligius prisoners with a few choice words and a rock.
- Deadpan Snarker: Murphy, as usual.
- Enemy Civil War: Echo notes that an enemy at war with itself is weaker, and she and others (especially Murphy) turn Diyoza and McCreary's sides against one another.
- Family of Choice: It has been mentioned already this season, but it is made painfully clear here that Clarke's family is Madi while Bellamy's is SpaceKru, and that their first priority is for their family, not necessarily each other.
- Flirting Under Fire: Shaw and Raven actively flirt in this episode, in the midst of plotting a breakout and Raven threatening to kill him if he doesn't comply.
- Gratuitous Latin: The title, "Sic semper tyrannis", is a Latin phrase meaning "Thus always to tyrants".
- Let Us Never Speak of This Again: Indra mentions the Dark Year and Octavia promptly shuts down the topic, again. Indra apologizes for letting the burden of that year fall entirely on Octavia.
- One-Liner: Murphy has several throughout the episode, often overlapping with Deadpan Snarker, as he instigates the riot (and again when he finds out that he didn't need to instigate the riot.)
- Single Tear: Octavia cries one by herself after she sentences two of the only people she loves in the world - Bellamy and Indra - along with Gaia, to fight to the death in the pits.
- Wham Line: Diyoza telling McCreary that she's pregnant and he's the father gives him enough pause for her to slash his neck with broken glass and escape.
