Despite the trials Betty underwent, she did not learn her lesson about loss. King Man explained that they learned valuable lessons as they found Jake's location with simply their minds. The exit door then appears, with King Man waiting outside, congratulating them for completing the maze and finding Jake. Jake then appears, happy to see his brothers. The past Betty then speaks to Betty about saving Simon, but Betty decides to change past Betty's flight, preventing her from meeting Simon, though this was just a trial and illusion, but did not actually change the past. Betty then said that she has spent so much time on Simon, that there may not even be any "her" left anymore. Jermaine suggests to Betty that she take time to herself, and a break from Simon. Betty did not take the trip as she met Simon the day after scheduling, and loved him so much that she dropped everything to help him find the Enchiridion. Before meeting Simon, Betty was going to spend six months studying in the Australian outback. The last part first appears as an empty, white void, but there is a lone window showing Betty's past, before she met Simon. Finn then climbs to the top to fight the Ice Thing, but falls off, landing on and breaking the chalkboard, leading to the third and final part of the maze. As Betty worked on it, Finn noticed that the Ice Thing changes the numbers on the chalkboard, as Betty gets close to solving it. Nevertheless, Betty began solving the equation. The Ice Thing appeared at the top, whom looked a bit threatening. At the end was a chalkboard with a long, advanced math equation, in which Betty decided to solve hoping it is their way out. The next part, was a pathway made of ice, with books and the like inside the ice. Finn then grabbed Jermaine and Betty as he ran them towards the next part. Betty looked in the eyes of the rest of the frogs, resembling Ice King, and they began to jump at them and attack. Finn looked the Fern Frog in the eyes, but the frog became hostile (or as Finn said, "outraged"), after looking into its eyes.
King Man shows Finn, Jermaine, and Betty, the Mars Temple, in which they can use to locate Jake, but what will need to go through a "three-part mind maze." They walk into the temple, many frogs appear in the shape of Ice King, but Finn notices one resembling Fern. Normal Man, now named King Man due to his position has King of Mars, then appears greeting Finn and Jermaine Finn was a bit angry at Betty upon seeing her, but forgave her quickly. The two arrive on Mars and quickly come across Betty, having not been seen since Elements. The brothers go to Normal Man's old house to use the Martian transporter and quickly arrive to Mars.
Finn was nervous, but then decided that Normal Man can help with the situation and decided to go to Mars. Frustrated and frightened, Jermaine tells Finn that he was worried about Jake because he dreamed that Jake was alone in space, running out of food.
Finn shows his brother the "BRB" note that Jake left, and told him he got it five weeks ago. Jermaine told Finn that he came over as he is worried about Jake. He then notices that Jake has returned, only to realize that it is not Jake, but his other brother, Jermaine. The episode begins with Finn struggling to put a giant bag of eggs into the fridge, as he does not have Jake to assist him. Searching for answers on Mars, Finn and Jermaine discover that they must first survive a cunning Martian mental trap.
