With Ava a wreck, Behrad and the Legends make a last-ditch effort to keep Sara from being abducted in the first place, even knowing that it will alter the timeline. Sara grapples with what she has just discovered about herself but is also shocked when Rory finds her on the mystery planet. With no time to spare, Sara, Mick and Gary devise a plan to help defeat Bishop. Meanwhile, Spooner envisions what her life would be like if she hadn't joined the Legends.

Behrad is disappointed because the Legends have forgotten his birthday, so when they track an alien pod to 2024 and wind up at his favorite television sitcom, he thinks it's really a surprise for him. Feeling guilty, Nate and Zari occupy Behrad by keeping up the ruse by attending a taping of the show while Ava, Spooner and Astra try to find the Alien to get the timeline back on track, which proves challenging. Meanwhile, Rory's behavior has been a little off, so Sara and Gary become determined to find out what happened, but Rory gets some unexpected news from his daughter, Lita.
