- Appropriated Appellation: Gravedigger took up his name because he was responsible for digging the graves of unidentified soldiers and because he literally buried every one of his enemies.
- Artistic License – Biology: You can't inherit traits from your great-uncle.
- But it's possible that more than one member of Gravedigger's family had the meta-gene. Gravedigger's was activated due to experiments. Jefferson's was because of the "vaccine".

- It's All About Me: Brandon makes it clear that he doesn't care about Markovia's war on Freeland or how the government might nuke the city to stop them, he just wants his revenge on Dr. Jace.
- Knight Templar: Gravedigger will "liberate" all metas, whether they want it or not.
- Leeroy Jenkins: Jennifer once again doesn't listen to her dad and tries to fight Gravedigger on her own, which almost ends in her death.
- Long-Lost Relative: Lynn discovers that Gravedigger is Jefferson's great-uncle. Leads to some Artistic License.
- Magical Defibrillator: Jefferson uses his powers that way to revive Jennifer.
- A Mother to Her Men: Lady Eve is very concerned over the wellbeing of her associate that Lala holds captive, enough to come meet him and tell him about Dr. Blair being the last one to have seen Tobias Whale.
- Motive Rant: Gravedigger has several throughout the episode.
- Navel-Deep Neckline: Anissa's wedding attire has a neckline that reaches her navel.

- Slasher Smile: Painkiller has one when he takes over Khalil's body.
- Superman Stays Out of Gotham: Apparently, it doesn't occur to Jefferson to call on his new super friends for help. It's a shame, because it seems like Barry or Kara or J'Onn or Clark would really come in handy here. Of course, maybe they'd come in too handy.
- In addition, for all of Gravedigger's talk about freeing metas, he seems to be laser-focused on Freeland, utterly ignoring Central City, which has plenty of metas as well.
- Super Powerful Genetics: Discussed. Brandon mentions that Jennifer's powers may be partly inherited from Jefferson, since apparently Brandon's missing father's powers were also earth-based. Also with the notion that Jefferson inherited his stable meta-gene from his great-uncle Gravedigger.
