The Last Hope " The Last Hope " is the 24th episode of . Summary . Kai , Jay , Cole , and Zane are practicing the use of their new elemental swords until Sensei Wu criticizes them for their recklessness , as their blasts could give away their location . The ninja then learn from Misako that , contrary to what she previously believed , there might be a way to stop the final battle : since removing the Helmet of Shadows from its pedestal within the clock started its countdown to the final battle , returning it could halt the clock . As such , she suggests that their efforts should be focused on retrieving the Helmet of Shadows from Garmadon . She enlists the ninja , except for Lloyd , to help her . At first , Lloyd is upset for being excluded yet again , but Sensei Wu reminds him that the whole point of the mission is trying to delay Lloyd fighting Lord Garmadon , and risking a meeting between the two could counter these efforts . Meanwhile , General Kozu was explaining the Stone Army ' s latest attempts to increase its defenses , which included the construction of some new vehicles . Garmadon is thrilled , but the Overlord reprimands him for having the army focus their efforts on Garmadon ' s ultimate weapon . During this discussion , the Overlord comments on how it appears that Garmadon does not want to face his son due to feelings towards him , causing Garmadon to get angry and fiercely order the Stone Warriors to get back to building his weapon , delighting the Overlord . The four ninja , disguised as Stone Warriors , offer Misako , who they claim to have captured , to General Kozu . Their inability to speak Kozu ' s language nearly leads to their ruse being uncovered , but Misako then angrily confronts Kozu , saying that the only way he could get her to speak is to bring her to Garmadon . Kozu , obviously angered , then drags her to Garmadon . Garmadon admits that he knows Misako wouldn ' t let herself simply get captured , and Misako tries to get him to turn good . Garmadon , however , exclaims that it is Lloyd ' s and his destiny , and that he will not back down . However , he takes off his helmet and sets it on a pedestal before talking about how Misako is the only one who understands him and asks her to join him . While he is talking and his back is turned , however , Misako steals the helmet and runs out of the tent . As this was happening , the four ninja , still in their disguises , were being ordered by Kozu to assist in the work on the Ultimate Weapon , which still remained largely covered . They do so , but Cole , getting aggravated by one of the Stone Warriors , knocks the Warrior off of the construct they were working from , blowing the cover . The ninja then fight several Stone Warriors before fleeing the construct , and meet up with Misako . Garmadon appears piloting a giant four - armed robot and attacks them , but Nya appears with the Power Drill and rescues them . The Overlord gets angry at Garmadon , saying that whoever wears the helmet controls the Stone Army , and Garmadon orders chase . The Stone Army pursues escapees through the hole created by the Power Drill , but the Power Drill escapes them and reemerges . Garmadon ' s robot , however , continues the pursuit and captures the drill in one of its hands . Before Garmadon can do any harm , the robot is destroyed by a powerful blast coming from Lloyd , and the group is freed . Lloyd walks over to the weakened Garmadon , and the ninja encourage Lloyd to finish him off while he ' s off vulnerable , but as Lloyd begins to do so , Garmadon appears saddened , and Lloyd doesn ' t have the heart . The Stone Army reappears , and Garmadon gives a triumphant grin , indicating that his apparent regret was a mere ruse . Lloyd escapes with the others in the Power Drill , and they head towards the clock . At the clock , the group marvels at its complex mechanics and Misako reveals that among the moving mechanisms is the pedestal upon which they need to place the helmet . The group attempts to find it , but the clock ' s mechanical complexity as well as interventions from the Stone Army means that , despite Misako finally finding the pedestal and placing the helmet on it , the group is moments too late , and the clock , albeit stopping momentarily , continues to move , with the hand already indicating that the final battle has begun . The clock ' s mechanisms line up to shine a bright light somewhere across the island , and Kozu confronts the heroes . The cliff begins to collapse and Nya is separated from the rest of the group and apprehended by the Stone Army . The others fall into the ocean below but survive . Lloyd regrets not defeating Garmadon when he had the chance and Cole attempts to comfort him , saying they all had a role in the current situation , and that it was " just the way the cookie crumbles " , which provokes Jay , who is still upset over the loss of Nya , to get mad at Cole , misinterpreting his choice of words as a deliberate and insensitive joke referencing the way the cliff " crumbled " . Both Kai and Jay want to rescue Nya , but Sensei Wu states that that time will come later , and that the group needs to get back to the Destiny ' s Bounty to prepare for the final battle , which could begin at any time . Across the island , at the place where the light from the clock shone , the Overlord reveals the completed Ultimate Weapon to Garmadon ( though the glare and blinding light prevents viewers from seeing it ) , who is thoroughly impressed .
