|The Last Stand, Part 1|
|Air date||August 10, 2018|
The Paladins receive a distress signal thats explained through a flashback to Pidge's father Sam's return to Earth four years earlier.
Voltron nears Earth, and Pidge tries to contact her father. She receives a recorded message from Samuel Holt telling them that the Galra Empire have invaded Earth, and they are preparing for their last stand.
Four years earlier, Sam Holt wakes in the Galaxy Garrison after being checked over, and is reunited with his wife, Colleen. Sam recounts his experiences with the Galra to the Galaxy Garrison's command staff, and warns them about a probable attack by the Galra on Earth. Sam advises them to warn the planet immediate. Admiral Sanda refuses to panic the world.
Commander Iverson and Sam begin analzying the Galra and Altean in an attempt to re-engineer the technology to provide defence for Earth. Sam meets the Garrison's top cadets – James Griffin, Nadia Rizavi, Ryan Kinkade, and Ina eifsdottir. With Sam's help, they begin upgrading Earth's defence capabilities.
A year later, Sam receives word from Matt that Voltron has disappeared, and that the Voltron Coalition was being targeted by the remnants of the Galra. Admiral Sanda orders Sam to break all communication with the outside galaxy in order to hide Earth's location. Sam argues that they should tell the world about the Galra, but Sanda again refuses.
Without authorization, Sam and Colleen broadcast the truth to the world. Sanda orders them arrested, but world comes in from around the planet. Instead of panic, the world offers its unswerving support.
Some times later, Sam is testing a new particle barrier at the Galaxy Garrison when the Galra arrive and being attacking Earth.
"The Galra didn't kill me, but your hug might!"
— Sam, in response to his wife's bone-crushing hug
