While investigating a mysterious bunker at Providence's Petting Zoo known as "The Hold," Rex and Noah stumble onto a formidable spider-like E.V.O. After White Knight locks down the Petting Zoo, Rex and Noah must make it to the exit alive. A panicky Noah lets slip that he works for White Knight, which rattles Rex so deeply that he loses the use of his powers. The two manage to make it to the exit, but while Noah apologizes for his deception the friendship seems over. However, after the spider snatches Noah from the threshold of safety, Rex's feelings of betrayal subside, and he proceeds to defeat the E.V.O. and rescue Noah. The E.V.O. is revealed to be Dr. Holiday's incurable sister. Rex threatens to deal with White Knight if he is spied upon again. Rex then resolves to leave Providence.

Rex y Noah son encerrados en el Zoo de la Providencia. Pero descubre que fue Caballero Blanco quien contrató a Noah para vigilar de Rex así poniendo en duda su amistad.
