Trivia

This is the first episode since The Flash: Seeing Red (2019), and the third since The Flash: The Icicle Cometh (2018), to feature Cecille, despite Danielle Nicolet being credited as a series regular. See more »

Goofs

The show has long since established its "rules" for time travel, and thus far, one of the most pivotal ones has always been that the person going back in time would also exist in the past to which they're travelling. This vital rule is completely shattered here, without so much as an attempt of an explanation for the deviation (not to mention how this "cheat" pretty much nullifies the whole premise of the plot).

Quotes

Cisco Ramon: Cisco Ramon, tonight you've got yourself a hot date and a meta-human cure. We're unstoppable.
[as he opens a breach, his computer beeps]
Cisco Ramon: Ohh, schrap.
