Barry is tormented by his vision of the future where Iris is murdered by Savitar. When a criminal named Plunder shows up in Central City, Barry recalls the villain’s presence in his vision of the future and fears that if he catches Plunder, it will cement Iris’ fate. Confused about Barry’s hesitation to stop Plunder, Wally decides to step in as Kid Flash. Caitlin offers Julian a job.
- Cisco mentions Caitlin "going all Frozen" on them, referencing the 2013 film in which the ice-powered protagonist loses control of her abilities and hurts her sister.
- Cisco quips "hang on McFly, I'm about to vibe you back to the future", referencing the protagonist, Marty McFly, from the Back to the Future franchise.
- Cisco and HR recite lines from a poem by Anna M. Pratt, as previously done in "Shade".
- One of the future headlines reads that Music Meister received a 6-figure deal. The Music Meister was a villain who debuted in the TV series Batman: The Brave and the Bold, and ended up appearing in person on The Flash in the episode "Duet".
- Barry's opening monologue for season 3 has changed starting from this episode, now mentioning Savitar rather than Zoom.
- This episode, being the first one after the Christmas break, alludes in multiple ways to its season two counterpart "Potential Energy": This concerns Barry's nightmares about a major villain (Savitar/Zoom) threatening the life of a loved one (Iris/Patty), the introduction of a "turtle" (as an animal/metahuman villain) and the cameo appearance of a dimensional/time traveler (Gypsy/Reverse Flash) who is wearing a projective device near the palm of the hand.
- Starting with this episode, Julian is now an official member of team Flash.
- This is the first new episode to air in the year 2017.
- This episode takes place about a month after the events of the previous episode, meaning it would place this episode somewhere at the end of January 2017, bringing it up to date of when this episode aired.
- It is revealed that the date that Barry traveled to in the future in the previous episode "The Present", was May 23, 2017.
- And since May 23, 2017 is a Tuesday, it ended up being Season 3 finale.
