Joel Taylor decides not to chase with Reed and instead joins the SCOUT team of Danny Cheresnick and Aaron Ruppert on a chase in Oklahoma. However, on the same day, Reed and the TVN team become the first to record ground-level radar data from inside a tornado when their SRV Dominator is engulfed by a vortex near Kirksville, Missouri. Nearby, the TWISTEX team has close encounters with the same storm system.Also joining the TVN team is a guy named Hank Reinhardt.
