What is primal season finale?

As an AI language model, my training data only goes up to August 2021, so I cannot provide information about the primal season finale if it happened after that date. However, if you are referring to the first season of the TV series "Primal" by Genndy Tartakovsky that aired in 2019, the season finale episode is titled "Plague of Madness." In this episode, the main characters, a caveman and a dinosaur, face off against a group of infected creatures who are spreading a deadly disease. The finale is intense, action-packed, and emotionally charged, as the two protagonists struggle to survive against seemingly insurmountable odds. The episode was well-received by critics and is considered a fitting conclusion to the season.
