S04:E34 - In His Majesty's Secret Service

Since the Cloud of Monstrox and Jestro are unaware of Clay’s situation, the NEXO KNIGHTS decide to let Clay go undercover and infiltrate the Stone Stompers. Clay gets the help of Jack Shield who is his majesty’s secret agent who is a specialist in infiltration and espionage. Clay has to undergo hard training in how to remain silent and unnoticed. Which is quite a challenge for a man in armor plates. Robin is intrigued by all the cool agent gadgets and follows Clay from a distance. Hidden. Clay convinces Jestro and the Cloud of Monstrox that he is still very evil, Jestro spills their master scheme of using the Forbidden Powers to unlock the Stone Colossus. They find Robin spying around outside their camp and Clay has to get rid of him. However Clay lets him go, and his cover is blown and he gets captured by General Garg. Luckily, the Nexo Knights in their Battle Suits has been following along not far away ready to intercept. Now is their moment. They manage to free Clay and fight the Stone Stompers. In that fight Clay is going “berserk” and the Knights are a bit shocked by this new chaotic behavior. When he fights Ruina (Witch) something holds him back. And we are left with wondering how that can be.
