Identity - Part 1
Isaac stops functioning. The crew of the Orville can't figure out how to help him. Captain Mercer, after consulting with the Admiral Halsey, sets a course for Kaylon 1, Isaac's home world.
The Orville arrives on Kaylon 1. They bring the comatose Isaac out of the ship with them. The Kaylons bring Isaac back online. Captain Mercer expresses thanks and invites Isaac to rejoin them aboard the Orville but Isaac says his mission is over.
Ty and Marcus, Dr. Finn's sons, are disappointed to learn that Isaac will not be coming back to the Orville. Isaac explains his reasons to them in person but it doesn't make them feel any better. Ty takes it especially hard. Dr. Finn is also very hurt by Isaac's decision to leave the Orville.
