Spear and Fang are separated and both find themselves drawn to others of their own kind.
Spear and Fang wash up on a shore, separated with no idea of where each other is. Fang finds a new friend, a tyrannosaur whose head is colored red. An injured Spear is taken in by a Celtic-like village and nursed back to health.
Red leads Fang to one of his hunting grounds — the village. He kills several villagers, and Fang begins to do likewise until she and Spear see each other. Spear stops the villagers from attacking the dinosaurs, and Fang interposes between him and Red, angrily blocking her new and old friends from attacking each other.
Despite this, Spear and Red battle furiously until Fang, trying to stop the fight, accidentally pushes Red onto a defensive battlement, killing him. Grief-stricken, she walks away from the village. Although the village chieftain urges Spear to stay, he follows Fang into the jungle.
This episode features the following tropes:
- Accidental Murder: Fang unintentionally kills Red when she kicks him away from Spear only to send him over a nearby ledge and onto a large wooden stake.
- Blue-and-Orange Morality: If dinosaurs can be understood to have a moral code that humans would recognize, Red's mindset is that of an alpha predator. Anything smaller than him is meat. He doesn't seem to even understand why Fang keeps stopping him from attacking Spear; he's just meat, after all...
- Cradling Your Kill: Moments after Red dies from his lethal injury that Fang unintentionally caused, she lowers herself down by nudging her head right beside his, showing that she's at least comforting him in his dying breaths.
- Dramatic Dislocation: Much of Spear's side of the story is his left arm being dislocated upon washing ashore, and the misunderstandings that come from the Celtic tribe attempting to fix it.
- Friend Versus Lover: Red considers Spear food and Spear considers Red a threat to the Celtic tribe. As the two try to kill each other, Fang continuously tries to force them apart. In interviews Tartakovsky explicitly refers to this as a love triangle.
- Fish out of Water: Despite finally being in the company of other humans, Spear finds himself just too different to fit in. He's ultimately more comfortable hanging out with a stray dog rather than the village chief's family.
- Immediate Sequel: The episode picks up the story where "Sea of Despair" left off, with Spear and Fang washing up the coast, separated.
- Medieval Prehistory: The episode takes place in a land where Celtic settlers coexist with prehistoric fauna, from various mammals to a Tyrannosaurus that preys on the humans.
- My God, What Have I Done?: Spear has this look on his face after he sees Fang nuzzling a dying Red so that he can pass on peacefully, realizing that he had contributed to the death of someone Fang loved.
- Poor Communication Kills: For as much as Spear and Fang can communicate to each other through broad vocalizations, Spear is unable to properly understand Fang when she tries to stop him from killing Red, which leads to him trying to kill Red after Fang seems to convince Red to stand down, escalating the conflict until Fang is forced to intervene once again, which leads to Fang accidentally killing Red. It's only after seeing Fang act affectionately towards Red as he's dying that Spear finally understands what Red meant to her.
- Reasonable Authority Figure: The Celtic chief recognizes that Spear is terrified and trying to protect himself, and quickly defuses the confrontation between him and the villagers.
- The Reveal: Spear's attempted escape from the village that revived him reveals that he and Fang wound up in ancient Ireland (or at least the equivalent of), amongst Celtic settlers.
- Tastes Like Friendship: This episode emphasizes how the sharing of food can ease tensions and forge emotional bonds.
- When Spear lashes out at the Celtic villages out of pain, fear, and confusion, the chieftain calms him down first by offering him water to drink and then a bowl of fruit. It works; after consuming both, Spear finally understands that the people pose no threat to him and acts more peacefully, allowing the healer to tend to the rest of his wounds.
- Spear is able to calm down a snarling dog, which soon enough submits and surrenders the haunch of meat it was eating. But rather than eat it all, the man splits the meat in half and shares it with the animal, allowing the two to bond.
- While things start off tense between Fang and Red, they quickly become amiable when the latter surrenders the rhino they had both killed. As he slinks off, Fang suddenly tosses him a hunk of meat for him to eat, similar to what she had done for Spear in the past. When he joins her in eating the body, she does not fight and they get along more peacefully from then on out.
- To Serve Man: Red is an active predator of humans, sneaking into the village at dawn and giving the impression he's done this before. Subverted with Fang as she's clearly surprised Red is hunting humans and only attacks one when they spear him.
- The Un-Smile: Having never seen a grin before, Spear attempts to do one after the chieftain's daughter does so. However, all it does is scare the girl into hiding behind her father.
- Unsuspectingly Soused: Upon Red introducing Fang to the fruit tree, they start eating fermented fruit off the ground beneath it and become quite obviously drunk.
- Yank the Dog's Chain: Spear and Fang both suffer this. They find members of their own kind and even manage to find some peace with them only for their respective groups to violently clash and they both leave heartbroken.
