The Theory of Everything (S08E15)

A deer is found shot illegally, and the suspect caught with its body in his truck has bizarrely dressed it in a tutu. The heavily intoxicated man is questioned by Nick and Brass but suddenly attempts to flee, prompting officers to use pepper spray on him. Unaffected, he is then tased, igniting in flames and leading to his death. Meanwhile, a woman in a tinfoil costume at the front desk warns everyone, including Nick, about an impending alien invasion. After the flaming incident, she is discovered dead, exhibiting green-tinted blood. As more victims appear with similar symptoms, the team must uncover the connection. Additionally, an elderly couple is found deceased in their sleep, suggesting a link between the cases.
