Grave Danger Grave Danger is the 8th episode in the fifth season , and the 52nd episode overall of " " . Official Description . " The Ninja use Ronin ' s airship to travel to the tomb of the First Spinjitzu Master in an underwater cave under the ocean , only to find out Morro is already there - and the Ninja must traverse the temple traps without the aid of the Sword of Sanctuary in a desperate attempt to get to the tomb first . " Plot . While the Ninja travels through the ocean in R . E . X . , Zane remarks that they ' re close to the Tomb of the First Spinjitzu Master . As Kai and Cole are worried about being underwater , Sensei Wu informs his pupils via video screen that he , Misako , and Nya are headed to their location on the Bounty , and that it ' ll be up to them to find the Realm Crystal before Morro , who is already ahead of them . After Misako tells them a riddle that might help them past the three tests , the Ninja are pursued by the Leviathan , which they manage to trap and escape successfully , while at the same time Morro is using the Sword of Sanctuary to foresee a trap in the tomb . Soon , the Ninja arrives at their destination , and almost immediately as they step foot on land Jay stumbles upon a piece of cloth that belonged to Morro , saying all the hopes that he wouldn ' t find it are gone . While Kai remains optimistic about their position , Zane finds a statue of the First Spinjitzu Master , and Cole ' s awestruck words accidentally trigger R . E . X . ' s auto - return , leaving the Ninja behind with no Aeroblades and no way out of the underwater tomb . Despite these odds , the team ventures forward to face the tomb ' s tests . Meanwhile on the surface , the Bounty has reached their location and awaits their return — even upon discovering Morro ' s minions are also there doing the same . Despite Nya ' s anxiety at their presence , Wu advises to simply be on alert and not provoke any attacks . While they ' re waiting , Wu questions Nya about her training , to which she absent - mindlessly answers her slow progress . This concerns Wu since her indifference is coming from her interactions with Ronin , but Misako reminds him that Nya has always been pressuring herself to her own set limits . The Ninja arrive in the first of the tomb ' s challenges : a circular room with sixteen doors , each with symbols on and above them . They quickly realize the procedure : choose the right door to proceed , or " end up in a realm of hurt " as Cole puts it . Jay notes the symbols around them as Kai questions the first part of Misako ' s clue for the tomb , leading him to one symbol that resembles a Spinjitzu tornado . As Jay heads for that door , Zane stops him in alarm as P . I . X . A . L . analyzes the symbols . Seeing a pattern , Zane explains the pattern : the whole room is a zoetrope , in which the symbols " on " the doors are slightly different from the previous and thus create a moving image when in motion . Therefore , he does what " a Spinjitzu master can " - Spinjitzu - and the motion creates one of the symbols that is apparently above the door they came in from . His choice proves to be the right one , as they find themselves in another underground hall to proceed . This time , the second room is a dead end , devoid of man - made structures except for on the other side : the Golden Staff of the First Spinjitzu Master . Sensing its implication , the Ninja become wary of the room ' s security and turn to Zane to sense any patterns or dangers ; but neither he nor P . I . X . A . L . can find any . Jay then points out the second part of the clue , what a Spinjitzu master " cannot " — which they find out once a step forward from Kai sets off well - hidden stone darts in their direction . Now with a better idea on the test ' s difficulty , Kai comes up with the idea of using Airjitzu instead of Spinjitzu to reach the staff , but the technique ' s temporary use stops him short and starts a long series of traps that corner and surround the others . Even so , the Fire Ninja remains undeterred in reaching the staff until Cole points out something crucial about the clue : since a ninja never gives up , it would make sense to use the staff to draw them away from their true objective . He then takes a literal leap of faith toward their only way out at that point - the chasm trap they made - and tells them to do the same , which Kai grudgingly does as well . Their fall sends them through a roller coaster of ice - crystal slides into an enormous maze , the third and final test . As Jay leads them due to his claim at being excellent with mazes , Kai and Zane see something extraordinary within a particular crystal wall : their reflections are much older and wearing the attire of a sensei . Although Kai becomes pessimistic about its implication , Zane clears it by explaining their reflections are actually images of their future selves , which Jay confirms when he notes he will have facial hair , an eyepatch , and be with Nya again , much to his elation : he keeps the last one to himself . Cole notes this could be connected to the clue ' s third part to not " look ahead , " but discovers he cannot see his own reflection even when beside Kai and Zane in the same crystal . Looking hard to find something of himself , he finally sees something - which happens to be Morro , who ambushes the Ninja while also traversing the maze . As they scramble to rejoin , Morro repeatedly attacks them with the Sword of Sanctuary , leaving them only with sliced crystal shards to counter his moves . After a while of back - and - forth attacks , Kai finally notices that as Morro breaks more shards , several more instantly take their place , providing him the successful idea of baiting the Master of Wind into trapping himself . Leaving the immobilized Morro behind , the Ninja proceed more confidently until Jay solves the third test ; they should not look forward or ahead , but " down " where tombs usually are found , and one area shows cracks where light is escaping . The foursome , after digging tirelessly , find themselves in one final cavern . This one is different from the others , as it contains an essence of every single element existing in Ninjago , as well as the tomb holding the remains of the First Spinjitzu Master himself . The Ninja kneel in respect for Ninjago ' s ultimate creator , and then Zane carefully extracts from his remains the object of their mission : the Realm Crystal . Upon its recovery , Morro shows up again demanding the Realm Crystal while holding a semi - conscious Lloyd at blade - point . Seeing how the odds are at a standoff , if not in Morro ' s favor , Cole vents his frustration which triggers the earth below him to rumble . Kai realizes their powers are returning now that Morro is no longer possessing Lloyd , albeit slowly , and comes up with a plan to even the odds . He converses with Morro before throwing him the crystal , prompting the Master of Wind to catch it while dropping Lloyd - and then drop it accidentally into a nearby stream due to the bottom being heated by Kai ' s weakened fire power . Enraged , he blows Lloyd into the stream as well , which carries both him and the crystal toward a nearby waterfall . Despite their fears of the water , Kai and Cole manage to rescue Lloyd from drowning , but not the Realm Crystal as Morro uses his Wind power to stop its fall while keeping Jay and Zane at bay . With the relic in hand , he escapes , leaving the Ninja reunited with their friend . Upon leaving the tomb , they find the Bounty also under attack with Nya struggling to keep up the wall of water that is protecting them from Soul Archer and Bansha ' s attacks . They soon have a reprieve when the ghosts crash their own boat from being distracted with their attack , but Morro then appears and the trio escape through a portal made by the Realm Crystal . As Wu , Nya , and Misako rejoice over Lloyd ' s recovery , Lloyd laments his inability to do more to stop Morro from succeeding , but Kai reminds him of his promise to watch over him as well as having him back on their side . The other Ninja back him up by showing their restored Elemental powers , declaring that even though Morro has his means of bringing the Preeminent to Ninjago , he has yet to see all of the Ninja at full strength .
