Hunk and Coran try to retrieve a new crystal from the Balmera while the rest of the team work to prevent Sendak from leaving the castle with Voltron.
While on the Balmera, Hunk and Coran meet local Balmerans, the siblings Shay and Rax, who help them hide from the Galra. Shay admires the two and wants to help them, but Rax is cautious and insists they leave. Hunk and Coran are able to sneak past the Galra to find a crystal, but are captured and imprisoned. Shay helps them escape with the crystal, but is captured by the Galra after her brother informs them of Shay's actions. Hunk promises to return and save her people before he and Coran return to Arus.
Still trapped outside the castle, Keith and Allura are unable to help Pidge take back the Castle. With Allura's guidance, Pidge is able to continuously sabotage the Castle's systems to further delay Sendak's take off. While this is all going on, Pidge's mind starts to wander. It is revealed that Pidge is actually a female named Katie Holt. In a flashback, Katie watches the news in horror as she learns of her father and brother's apparent demise on the mission to Kerberos. Katie breaks into the Galaxy Garrison and accesses Commander Iverson's files of the mission. When she is caught by Iverson, she presses him about the crash despite not finding anything incriminating in her probe. Iverson reprimands her and bans her from ever entering the Garrison again. Some time later, Katie enrolls in the Garrison, but cuts her hair and wears glasses, passing herself off as a male student named Pidge Gunderson.
The mice are able to take down the particle barrier, allowing Allura and Keith to enter the Castle and help Pidge against Sendak. With Lance in recovery and Sendak imprisoned, Pidge decides to remain on the team.
"Hasta la later, Keith!"
— Lance, excited he made it as a fighter pilot
"Hello? Pizza? Girls? Astronauts?!"
— Lance tries to figure out how to bond with Pidge, she just ignores him
- Coran mentions they would have a harder time collecting a crystal from a Weblum's belly, which Hunk and Keith would do in The Belly of the Weblum.
