"Knocked Down, Knocked Up" is the series finale of the American science fiction television series Legends of Tomorrow, revolving around the eponymous team of superheroes and their time traveling adventures. It is the thirteenth episode of the seventh season, and the series' 110th episode overall. The series is set in the Arrowverse, sharing continuity with the other television series of the universe. The episode was written by Phil Klemmer and Keto Shimizu, and directed by Kevin Mock. It premiered on March 2, 2022, on The CW. 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.
