Lego Nexo Knights Season 4 Episode 8 Between a Rock and a Hard Place Episode Title:Between a Rock and a Hard Place.Episode Description:Recapping from the previous episode, Merlok 2.0 reveals that Ruina was not only Clay's mother, but also Merlok's sister and fellow magic user and Wizard's Council member Wanda Moorington, who was originally pure-hearted until Monstrox's presence corrupted her, forcing Merlok to petrify her. As he is also Clay's uncle, Merlok become Clay's parental guardian while refraining from telling Clay about his inherent powers due to fear that he would end up like Ruina. Elsewhere, Jestro and the Cloud of Monstrox have obtained the final and most powerful Forbidden Power known as the Forbidden Power of Awesome Annihilation (which can reduce an entire town to ruins with a single explosive blast). After adapting to the combinations of their vehicles and battle suits, the Nexo Knights attempt to prevent the Stone Monster Army from transferring the last Forbidden Power into Mount Thunderstrox. Alas, the Forbidden Power of Awesome Annihilation is transferred into the last pillar atop Mount Thunderstrox and through the process of a lengthy and powerful electrical storm that started as a result, Mount Thunderstrox is destroyed as the Stone Colossus of Ultimate Destruction awakens from within it. When the process is complete, the Cloud of Monstrox enters and possesses the Colossus of Ultimate Destruction and immediately relieves Jestro and Roberto of their duties, believing their usefulness has expired and that he no longer needs to take orders from them. As the Colossus of Ultimate Destruction marches towards a nearby town, Aaron is unsure how to defeat it. Back in the Fortrex, Clay's petrified body begins cracking as an unnatural blue glow is emitted from it.
