- Arc Welding: Turns out Sue is also after Black Hole, due to them blackmailing her parents.
- Artistic License – Physics: Joe jumping out of a car that is going 120 mph without any injuries is...not very realistic to say the least.
- Awful Wedded Life: It is clear from their conversation that Eva and Joseph were not happy even before she disappeared into the mirror, and actually harbored some genuine hatred for each other.

- I Never Said It Was Poison: Carver saying Ragdoll using a box to hide, even though Joe never told him.

- Immune to Bullets: Ragdoll uses his powers to catapult a barrage of bullets back at Joe.
- Lyrical Dissonance: Not so much a lyric, but the music becomes more chaotic and discordant as Barry begins to piece together that the Iris he's been living with is not the Iris he loves, until it's a veritable cacophony of disturbing pitches.
- No-Sell: Sunshine is utterly unimpressed with Joe's pleas to help him get Carver.

- Papa Wolf: When Joseph entertains the idea of harming Cecile and Jenna, this earned him a punch to the face from Joe.
