In Let's Deal with Our Stuff!, Seth came to Bay City High to announce his scholarship, Harper Grant for Young Futurists. Seth came to Cassie since she filmed MECH-X4's fight. Cassie agreed and she interviewed everyone, including Ryan, Harris, Spyder, and Mark. Seth promoted that he was going to put it on every Harper Smartphone to make up for her not filming MECH-X4 against Octoconda.
In Let's Go Clubbing!, Cassie figured out that Ryan was the pilot due to recent things that were happening. Cassie went inside the fan club and told them about the theory of pilots being in Mech-X4 and said it was Ryan's idea. Ryan told the rest of the people that he said pirates, not pilots so that they won't believe there're actually pilots on Mech-X4. Ryan showed Cassie that he wasn't a pilot by getting out of the robot and controlling it outside.
In Let's Destroy Some Ooze!, Cassie was at Bay City High at 4 am and witnessed Mech-X4 destroying Bay City High. She was filming Mech-X4 destroy the school and shared it on Gramogram.
