Sacrifices and hard choices must be made when the crew of the Galaxy One face off against Lord Commander to close the disturbance and save Mooncake.
Tropes:
- Abandon Ship: After having been damaged and repaired again multiple times throughout the season, the Galaxy One is finally destroyed beyond repair. HUE has to convince Gary that abandoning the ship is the only logical option left. Gary however choses to crash the Galaxy One into the Lord Commander’s ship, stating that if they go down they will go down big.
- All for Nothing: Ultimately, the heroes cannot prevent the Earth from being pulled into Final Space. On the flip side, neither does the Lord Commander achieve his goal of entering Final Space and becoming a Titan. Thus, the heroes and villains both failed.
- And There Was Much Rejoicing: Played straight with Gary but inverted with Mooncake; The former cries Tears of Joy when seeing KVN die, and the latter is shocked when seeing his corpse.
- Apocalypse How: The entire Earth is pulled into final space by one of the Titans.
- Big Damn Kiss: Quinn and Gary exchange one right before Quinn boards the Hawk to bring the anti-matter bomb to the breach.
- Big "NO!": The Lord Commander when the Titan he just freed ignores him completely, proving Gary was right and the Titans never chose the Lord Commander to make him one of them.
- Brain Uploading: When the Galaxy One is destroyed, HUE uploads himself to Gary’s helmet.
- The Chosen One: The Lord Commander believes himself to be one for the Titans. Gary counters these claims by stating the Lord Commander got his powers entirely by accident. He’s proven right when the Titans begin to break out of Final Space, but completely ignore the Lord Commander.
- Deflector Shields: The Galaxy One has these, and deploys them against the Lord Commander’s hive ships.
- Downer Ending: Quinn and the Earth are trapped in Final Space, KVN is dead, Tribore, Little Cato and Gary's fates are unknown, the Galaxy One is destroyed, and Mooncake is still back at the Lord Commander's ship. The Lord Commander will probably die soon, but this does nothing to change the fact.
- Dying Vocal Change: Happens to KVN as he dies.
- Forgot About His Powers: Tribore forgot he is still the leader of the resistance. It’s not until he moans they really need a resistance to face the Lord Commander that he remembers, and calls them for backup.
- Half the Man He Used to Be: One of the SAMES accompanying Little Cato’s ship gets blasted in half.
- Heroic Sacrifice: Quinn makes one to detonate the anti-matter bomb and close the breach, just like how John Goodspeed did years earlier.
- Hot Paint Job: Tribore paints some flames on the anti-matter bomb to make it look cooler.
- Horde of Alien Locusts: The Lord Commander’s hive ships; thousands of small robots that act like a swarm of bees.
- How We Got Here: This episode finally ends the season long how we got here scenario, and shows how Gary ended up drifting in space with his oxygen running out.
- Internal Reveal: The Lord Commander learns that Gary is the son of his late friend John Goodspeed.
- It Has Been an Honor: Gary gives one of these speeches to the Galaxy One crew before they engage the entire fleet of the Lord Commander, telling them how he came to regard them as family, and he wouldn’t be who he is today without them.
- Just a Kid: Quinn doesn’t approve of Little Cato going out first to clear a path through the Hives for a Hawk carrying the anti-matter bomb, citing it’s no job for a kid. Gary defends Little Cato however, pointing out how mature the boy has become.
- Little "No": Gary utters one when he realizes Quinn is about to set off the anti-matter bomb on her own and doesn't expect to live in completing the deed. No doubt he's flashing back to the time his father did the same thing.
- That Man Is Dead: The Lord Commander no longer listens to his old name, Jack, stating that person died when he was chosen by the titans.
- Nice Job Breaking It, Hero: Gary crashing the Galaxy One into the Lord Commander’s ship prevents Little Cato from shooting the Lord Commander, and instead causes Little Cato to be hurled into space.
- Oh, Crap!: The Lord Commander's reaction just before the Galaxy One’s lightfold engine explodes.
- Mooncake when he notices KVN's body, and then when he gets pulled into the Lord Commander's ship by a tractor beam.
- The Lord Commander again gets this reaction along with Little Cato when they notice the Galaxy One just about to ram the spot they're in.
- Our Hero Is Dead: This is presumed to be Gary's (looming) fate when his suit finally runs out of oxygen.
- Previously on…: The episode starts with one.
- Ramming Always Works: Gary rams the Lord Commander’s ship with the Galaxy One.
- "Ray of Hope" Ending: Almost literally played straight when a mysterious light shines on Gary's body at the end of the credits.
- Say My Name: Gary screams out for Quinn in desperation just before the portal to Final Space explodes, and tries to get HUE to get her back online to no avail.
- Tears of Joy: Gary sheds some when KVN is destroyed.
- Uncertain Doom: At the end of the episode, Gary is drifting aimlessly in space with his oxygen supply finally reaching its limit. He finds himself in a white void (presumably the afterlife), where his father offers him a choice of where to go next. Quinn has traveled further into the portal to Final Space and is presumed dead after detonating the anti-matter bomb to close it. Little Cato has been blasted into space and is as far as we know also floating around somewhere. The Lord Commander lost his entire fleet and is presumably still dying on board the remains of his ship. Tribore’s ship has been shot but it’s unknown if Tribore survived or not, with his resistance fleet's fate just as unclear. And Mooncake is still a prisoner on board the Lord Commander’s ship.
- Weapon of Mass Destruction: A lightfold engine, when ejected from the ship and detonated, can cause an explosion capable of crippling an entire fleet of space ships. At HUE’s advice, the protagonists to this against the Lord Commander’s armada, leaving only the Lord Commander’s own ship intact.
- You Have GOT to Be Kidding Me!: The Lord Commander says this when he sees the breach to Final Space being closed.
- You Shall Not Pass!: Mooncake and KVN (the latter only because HUE threatened him into it) hold off the Hive ships that break through the Galaxy One’s shields while the others come up with a plan to get the anti-matter bomb to the breach.
- Zerg Rush: The individual Hives are pretty small, and can easily be dispatched even with a handheld firearm. It's their sheer number that makes them so dangerous.
