Plot 

Gary Green, having been sent flying out of the Waverider, ultimately lands in 30,000 B.C., but manages to returns to the manor. The Legends learn that Gwyn Davies died at the fixed point in 1916 Mametz Wood, France. Gary deduces that Sara Lance is pregnant (due to her alien biology) and her regenerative abilities transfer to the baby. The Legends travel to before Gwyn's death, but are intercepted by Gideon who tells them to leave. Astra Logue and Spooner Cruz convince her to turn against AI Gideon, who uploads herself into a clone body. Gideon disables the Waveriders cloaking, causing her clone to become an anomaly. She self-destructs in the Temporal Zone, but Astra shields her group and rebuilds the Waverider.

The others meet with Mike, the Fixer. Gwyn states that anyone attempting to change the battle would be erased in a time paradox making Mike feel useless. He destroys Gwyn's machine and steals the Waverider to talk to his superiors. Nate Heywood rescues Alun, but is permanently depowered by mustard gas. Afterward, Sara reveals her pregnancy to Ava Sharpe, while Nate retires to the Wind Totem to settle down with Zari Tomaz who has also retired from the team. Mike returns with the Waverider, but he and the Legends are arrested by his superiors.

Production

Writing 
The episode was co-written by Phil Klemmer and Keto Shimizu. In an interview with SyFy Wire, Klemmer said that they had the intent to include Booster Gold in the series ever since its inception. If the series was renewed then the character would have reappeared: Klemmer said, "It's just interesting to imagine what his dynamic is going to be with the team". While the episode was not intended to be the series finale, it ended up being so as the series was not renewed.

Casting 
The episodes saw appearances from main cast members Caity Lotz, Tala Ashe, Jes Macallan, Olivia Swann, Adam Tsekhman, Shayan Sobhian, Lisseth Chavez, Amy Louise Pemberton, Nick Zano and Matt Ryan playing Sara Lance, Zari Tarazi, Ava Sharpe, Astra Logue, Gary Green, Behrad Tarazi, Spooner Cruz, both human and AI Gideon, Nate Heywood, and Gwyn Davies respectively.

On February 22, it was announced that Donald Faison would be guest starring in an undisclosed role. Later when the episode was released it was announced that this role would be as Booster Gold. Tom Forbes guest stars as Alun Thomas. Had the series been renewed for another season than this would have been Zano's final appearance as a series regular.

Filming 
Filming on the episode began on December 3, 2021 and concluded on December 16. In an interview, the director Kevin Mock said that a few of Faison's scenes were not in the original script but added due to the fact that they enjoyed working together.
