Now knowing that Gaylen's Core was entrusted to the Trolls, the crew need to find it before Morando does.
Tropes for this episode include:
- The Cameo: Knowing that Gaylen's Core was entrusted to Kanjigar and Vendel, Aja and Krel have Toby call Jim and Blinky. We see them in Hoboken fighting a masked warrior.
- Continuity Nod:
- Stuart explains the Legend of Gaylen's Core as recounted in "A Brief Recapitulation of Akaridion Lore", Toby remarks on the fact that the Trolls also have their own similarly titled book.
- Toby mentions that Jim was the only one who made it out of The Deep.
- Downer Ending: Morando has stolen Gaylen's core, and the Tarrons failed their mission.
- Face Your Fears: Krel has to face his fear when he went into The Deep.
- Ironic Echo: Varvatos throws Krel into The Deep, saying that he's being incentive. Later on, Aaaaarrrgggh! throws Varvatos into The Deep by saying that he's being incentive.
- Our Zombies Are Different: Apparently the destruction of the Hearthstone allows for the animation of dead Gumm-Gumm trolls.
- The Reveal: The Deep wasn't made specifically to be a prison, but to hide Gaylen's Core.
- Unusually Uninteresting Sight: Jim and Blinky doesn't seem to mind that Aja and Krel are aliens while they're fighting in New Jersey. Granted they had bigger priorities at the time, but still.
