Radar notifies Jesse of an upcoming adventure with Petra. Jesse helps citizens prepare for Founding Day before meeting her. Their meeting place self-destructs to reveal a bottomless pit; but they escape. Petra finds Jack, who can help Jesse remove the gauntlet and the heckmouth. Jack reveals that the gauntlet is tracked to an Ocean Monument, and that a "Structure Block" can close the pit. Jesse convinces Jack to take them and Petra to it. At the monument's centre, the Admin appears and attempts to kill them, however they and their companions escape to where the Admin reappears.
After Jesse defeats it, the Admin returns and challenges Jesse's group to reclaim the clock (later destroyed by Jack/Petra) in his ice palace, who they then head towards, later joined by Stella and Lluna. Jesse resolves with their friends to find "Prisoner X" (later revealed as Xara), who apparently knows how to escape the maze. Jesse opens their cell before they combat whomever destroyed the clock and then with Xara, attack the Admin. Jesse convinces her to help and escape the institute. Xara then shows them a portal which she repowers. They along with Petra arrived at the "Terminal Space". Jesse, Jack, and Petra reaches it and finally Jesse enters it and defeats Romeo.
