Plague of Madness

In a tranquil valley, an herd of Argentinosaurus are living their lives when one of their number is bitten by an insane zombified Parasaurolophus which bites one Argentinosaurus before being killed by it. Shortly afterward, the Argentinosaurus becomes a zombie itself, going on a rampage and massacring its herd.

Sometime later, Spear and Fang stumble across the aftermath of the slaughter, disturbed by the many corpses and how they are untouched by scavengers or flies; a curious Fang sniffs one body before recoiling in terror, before the Argentinosaurus rises up behind the duo. Horrified, the two immediately flee through the jungle into a ravine, where the Argentinosaurus knocks itself out, and Spear and Fang rest in a cave. That night, Spear has a nightmare of the Argentinosaurus reviving and infecting him and Fang, and on awakening, decides to convince Fang to leave for night, lest his nightmare come to pass. As they make their way across the ravine, the Argentinosaurus awakens and continues its pursuit of them.

As Spear and Fang escape through a crevasse too narrow for the Argentinosaurus, they begin to make their way across a volcanic plain, doing so carefully until the Argentinosaurus tears its body apart to break free and pursue them again. On being burned by a lava geyser, the Argentinosaurus jumps towards them, breaking through the crust into the lava below, and allowing Spear and Fang to ride a wave to safer ground and resume running, as the Argentinosaurus repeatedly re-emerges and sinks, unable to climb out but still pursuing them. As the Argentinosaurus is slowly incinerated to ash, Spear and Fang observe its final agonizing moments in shared grief and dismay.{{cite web |url=https://www.cbr.com/primals-latest-episodes-best-halloween-viewing |title=Primal{{'}}s Latest Episodes Are the Best Halloween Viewing of the Season |website=Comic Book Resources |date=October 29, 2020 |access-date=October 29, 2020 |last=Stewart |first=Brenton}}
