Rage against the dying of the light.
Spear and Fang take Mira back to her homeland, while an old enemy follows them with vengeance on his mind.This episode features the following tropes:
- Babies Ever After: The epilogue shows that Spear ends up fathering a daughter with Mira, who takes up many of her father's traits.
- Bittersweet Ending: The Chieftain has finally been defeated for good and is dragged back down into the underworld, ensuring that he'll never menace the heroes again... but it's a victory with a heavy cost, as Spear ends up giving his life in the process. Spear's survived by the daughter he and Mira conceived together, who grows up alongside Fang's babies.
- Book Ends:
- The first episode has Spear's family dying and leaving him as the Sole Survivor while Fang's babies go the same way. Here, while Fang does not die, Spear does, and ultimately his and Mira's daughter grows up to adulthood alongside Fang's babies.
- After losing his family in episode 1, Spear contemplates suicide by jumping off a cliff. In the final episode, he saves his new family by tackling the Chieftain off a cliff at the expense of his life.
- The first episode of Season 1 ended with Spear atop Fang's back, with the latter roaring, marking their epic bond and companionship. The final episode of Season 2 ends with Spear and Mira's daughter yelling alongside one of Fang's children as she rides atop one of them.
- The first and the last spoken words in the series are the same: "Mira".
- Defiant to the End: When they are cornered by the Chieftain atop the mountain, rather than look for an escape route Spear and Fang roar a challenge. Taken to its extreme when after Fang is hit, an enraged Spear launches at the Viking and responds to being set ablaze by shoving him off a cliff, beating him down every inch of the way.
- Diabolus ex Machina: From the heroes' perspective, outside their singular encounter with the remote coven, there has been no indication of magic or the supernatural in their adventures so far, and Spear and Fang thoroughly decimated all the viking raiders, leaving nobody alive to hunt them down for revenge or to recapture Mira. Just when they're settling down and starting to build a new life in peace amongst Mira's community, thanks to the otherwise-uninvolved Scorpion, the Chieftain returns as a flaming Magma Man, utterly invincible and beyond their ability to combat such an unknown foe, requiring Spear to eventually sacrifice himself to stop him from destroying everything, even when he'd all but been guaranteed a happy ending.
- Disney Death: Just as Amara is blown away to reunite with her, Mira is likewise surprised to see Amara again. And one can't blame Mira's shock: last time she saw her friend, she was axed in the back by a viking.
- Dragged Off to Hell: After the Chieftain gravelly injures Spear, the Scorpion's fist reaches up, grabs the Chieftain in his human form, and drags him back down into the afterlife.
- Fan Disservice: Any sexiness in the final moments between Spear and Mira is undermined by him being covered in horrifying and deadly burns and being unable to move.
- Fish out of Water: As with the Celtic tribe, Spear ultimately feels uncomfortable among Mira's people, and retreats from a gathering to be with Fang. The cave paintings he draws on the walls of the house suggests not even Fang truly assuages his loneliness, as he draws himself standing apart from her and her babies.
- Grand Finale: Serves as one for Spear's story, which ends with him sacrificing his life to save everyone in the land, and leaving a legacy being his new daughter.
- The Hero Dies: After many struggles, Spear finally falls in a battle against a supernaturally enhanced Chieftain. Although to say he goes down swinging is an understatement.
- Howl of Sorrow: When Fang realizes Spear can't be saved, both she and her babies roar in grief, howling into the night as she storms out of the hut and into the village.
- Infernal Retaliation: After seeing Fang get blasted by the Chieftain, Spear charges him in a mad rush and even getting set on fire doesn't do much to slow him down, knocking the Chieftain off the mountain while pummeling him all the way to the bottom.
- Laser-Guided Karma: Mira's Flashback as to her capture by the Vikings shows that despite the complete obliteration of their village, that eventually resulted, several of them were very deserving of their fates.
- The Horned viking that Spear interrogated and terrified into fleeing for his life is shown to be the one that killed Mira's past lover, and violently strangled her into submission in anger when she kicked him in the face, making his humiliating death against a stronger female quite poetic.
- The bald moustached viking that lead the raiding party back to the village is revealed to be the one that branded Mira's head, making his decapitation at her hands very deserving.
- The Chieftain is revealed to be the one that lead the search efforts to reacquire Mira, even after she escaped to a foreign and deadly land and despite the risks, out of anger at being humiliated by her escape. His determination to avenge the wrongs and slights against him, without ever considering the consequences, resulted in his entire people being wiped out, his own death, and his eventual eternal damnation, all from his inability to recognise his own hand in his suffering or back down from pursuing his goals.
- A Minor Kidroduction: The episode begins with a flashback to Spear as a kid painting on a wall with his father shortly before the Smilodon attack.
- Oh, Crap!: The Chieftain's eyes go wide in his fire giant form when Spear charges at him despite being set on fire.
- Out with a Bang: Mira conceives a child with Spear right as the latter lays dying.
- Questionable Consent: Mira just climbs on top of a dying Spear without any warning. Spear doesn't seem to mind but he's not in the right state to fully consent to the encounter.
- Second Love: Spear and Mira ultimately become this to each other—while Spear had lost his mate (and their children) all the way back in the first episode, Mira's revealed to have lost a lover in the Viking-attack that initially enslaved her (which is also what ultimately led to her meeting Spear in the first place).
- Shown Their Work: Neanderthals and Homo sapiens can and did reproduce with each other, as Spear and Mira demonstrate.
- Someone to Remember Him By: Standing over Spear's deathbed, surrounded by his paintings of his life story, Mira seemingly resolves to continue his story by invoking this trope, engaging in sex with Spear as he dies. She succeeds, and we cut to their daughter several years later.
- Taking You with Me: As the Viking Chieftain sets Spear on fire, the caveman charges at him with a primal roar, looking like a blazing demon himself, and they both tumble down the cliff in mortal combat. They both survive the fall, but the Chieftain is Dragged Off to Hell, and Spear eventually dies from his burns.
- Trauma Button: Seeing the site where the Vikings killed her boyfriend and kidnapped her is enough to prompt Mira to fall to the ground in tears.
- Trauma Conga Line: Mira's backstory is fully explored in a flashback, and it's not pretty. When the Vikings came, she first-hand witnessed her friend (seemingly) die, her boyfriend was summarily cut down before her eyes, she was taken from her homeland, painfully branded, and made a slave. The only happy thing that happens is that she was lucky enough to get ahold of an axe and use it to cut her chains and swim to freedom.
- What Happened to the Mouse?: The flashback to Spear's original tribe raises more questions than answers. The last we see of them is the survivors fastening his father's necklace on him, suggesting that he's their new leader — yet by the first episode of the series, Spear no longer has the necklace, and lives only with his wife and their children, with seemingly no other humans of his species seen for the rest of the show. Considering what we've seen of Spear's world in other episodes however, their fate is easy to deduce.
- Why Did It Have to Be Snakes?: Literally - when chasing Spear and Fang, the Chieftain transforms into a giant serpent, which visibly unsettles Fang, who developed a phobia of snakes all the way back in the second episode.
