Episode Title:
Heart of Stone.
Episode Description:
After Clay goes into another frenzy during a training session, Lance is convinced that Aaron needs help being a leader. Meanwhile, Jestro and the Cloud of Monstrox have obtained the Roguls associated with the Forbidden Powers of Malicious Melting (which melts its target), Evil Evaporate (which evaporates water) and Confounding Confusion (which eliminates the victim's intelligence). Although they succeed in transferring the first two into the pillars atop Mount Thunderstrox, the Nexo Knights track them as they are headed to transfer the last one. Clay goes into another frenzy and destroys the Forbidden Power of Confounding Confusion, only to attempt to kill Ruina who reveals that she is Clay's mother and cursed Clay in hopes that he would follow in her footsteps. Returning to the Fortrex, Merlok 2.0 confirms that Ruina was telling the truth and that Clay possesses magical abilities that could even surpass his own. Realizing that his rage can no longer be controlled, Clay uses his newfound magic to give Macy a Nexo Power that forces her to return him to his inanimate state, much to Macy's misery.
