The Why of Fry
From Futurama Wiki
While walking Nibbler, Fry feels that he is useless, only to have Nibbler tell him otherwise. Nibbler knocks Fry out, drags him to his small spaceship, and takes him to Eternium. After being introduced to the Nibblonians, Fry's importance is revealed. He has a unique genetic disorder which has resulted in him lacking the Delta Brainwave due to him becoming his own grandfather. This rendered him immune to the attack of the Brainspawn a few months ago, an attack which no-one else on Earth remembers.
The Nibblonians reveal the Brainspawn's plan to collect all knowledge in the universe, and then destroy it. Fry, because of his immunity, is the only person who can stop them. The Nibblonians have made a "Quantum Interface Bomb" which will send the InfoSphere into an alternate dimension forever, and Fry's mission is to implant it inside the InfoSphere. They bring Fry to the InfoSphere just as it collects the last data. It then opens to scan itself, the final piece of information. This is the only chance to get in. The Nibblonians send Fry in on the Scooty Puff, Jr.
Fry arrives at the center of the sphere, rendered invisible by his genetic abnormality. He is about to activate the bomb, but realizes that while he is here, he can find the answers to any question in the universe. He asks questions about "postage for stamp glue" and "what killed the dinosaurs" to the Infosphere. He is discovered and the Brainspawn try to stop him, but his immunity protects him. He plants the bomb and tries to escape, but the Scooty Puff Jr. falls apart, trapping him. Fry is doomed to enter the alternate universe with the Brainspawn, but is glad that his life had a purpose: "leading good to victory over evil".
The Brainspawn question his motivation, suggesting that the Nibblonians are not as good as they appear. They offer to show Fry something that happened the night Fry was frozen on December 31st, 1999. It is revealed that Nibbler unbalanced the chair that Fry was sitting on that night, tipping him into the cryogenic chamber and bringing him to the future. Nibbler explains that Fry was the only person who could carry out the mission against the Brainspawn's Infosphere, but that he would have died of old age almost a thousand years before the mission was to take place, so they had to freeze him to bring him to the year 3000, and save the entire universe. Fry does not disable the bomb and he and the Infosphere are sent to the alternate universe.
Meanwhile, Leela is on a date with Chaz, the mayor's aide. Chaz reserves the rocket ice rink specially for Leela, denying its use to the orphans who were supposed to visit the rink. Leela, having grown up as an orphan herself, tries to persuade Chaz to allow the orphans to use the ice rink, but he refuses. Leela realizes that Chaz abuses his position and completely ignores the needy. She shoves his badge in his mouth and leaves.
In the other dimension, the Brainspawn realize they can send only Fry back in time to stop Nibbler from freezing him. Fry accepts their offer and is transported to the cryogenics lab. He appears behind Nibbler under the desk, just before his past self is frozen. He restrains Nibbler, who protests that Fry must be sent to the future to stop the Brainspawn. Fry assumes that Nibbler has traveled through time as well, but Nibbler explains that his people lack that ability, but are very long-lived, and Fry first met Nibbler when he was a thousand years older. Nibbler asks if there is anything he wants to save in the future and Fry realizes the only thing worth saving in the future is Leela. Fry mentions this to Nibbler, who mysteriously notes that Leela may be the "Other", and advises Fry not to give up on her. He promises if Fry makes the right choice, back in the 31st century Nibbler will help Fry win Leela's heart. Fry gives in, and unbalances the chair himself, freezing his past self. Before he fades away, he yells "Just remember the Scooty Puff Jr. sucks!". Nibbler then vows that "in a thousand years, I'll get right on it".
In the future, Fry escapes the InfoSphere on a Scooty Puff Sr. and Nibbler returns Fry to Earth, then blanks Fry's mind of what happened, but not before handing Fry a flower. Back at Planet Express, Fry gives Leela the flower. The episode ends with Leela giving Fry a kiss.
