- Major Grey leads her elite commandos in attacking Gambi's shop and the Sanctum to retrieve the briefcase.
- A subtle one, but when Khalil attacks Painkiller, he does so in the former's training facility, not in the hallway outside his mother's apartment, where they've fought their previous battles.
- And Your Little Dog, Too!: In a direct contrast to his previous behaviour of leaving Khalil's mother be back in season 2, Tobias threatens Nurse Allen by having already murdered his father and threatening the life of his mother. By the end of the episode, he's also killed Allen himself.
- Back for the Finale: Commander Williams returns for the first time since his defeat by Black Lightning.

- He Knows Too Much: Commander Williams's orders to destroy all sensitive information in Freeland includes killing Dr. Jace and Lynn, with him succeeding in the former.
- Heroic BSoD: When Jefferson asks Lynn what happened to Commander Williams, all she can offer is "I don't want to talk about it."

- Khalil brings it to Painkiller on his own turf. The result appears to be a Wild Card if not an outright Anti-Hero.
