During the fourth day, Chris and Kelly are violently assaulted in their house and then reveal to be held hostages by Mitch Conner, who uses them in order to blackmail The New Kid do they can do chores for him. Mitch then lies to Butthole, as he isn't going to set their parents free.
When travelling through Mephesto's lab, the New Kid finds a room, where both Chris and Kelly are locked up. To pass through to the next room, the New Kid needs DNA from one of the parents. This involves either cutting off Chris's head or Kelly's arm, both of which will result in one of them dying. The New Kid then puts the head/arm in the scanner and can pass through.
Is later revealed that Mitch Conner took Chris and Kelly to Dr. Mephesto's laboratory, there, Kelly was attacked by Mutant Sixth Graders who broke her legs and almost ripped her left arm apart, incapacitating her as a result while Chris is placed naked on a surgical table while being trapped by a tube brace.
After surviving the many horrors of the laboratory (as Mitch Conner had deactivated the security measures), The New Kid comes across their parents. Chris informs the New Kid that they are trying to extract an organic DNA sample from one of them. Kelly informs her child that the scientists were just about to cut Chris' head off and that the only way to proceed is to finish the job, Chris hears this and insults her. After hearing what his wife says, Chris insults Kelly for not being able to keep quiet about their child powers and tells them to use their mother's arm as an organic DNA sample. The New Kid then has to kill one of them while they both beg them to spare their lives.
In “Farts of Future Past”, the New Kid finds himself going back in time to the Origin story. He goes into the parents' bedroom, where, after seeing 2 versions of his child, Chris explains the New Kid's backstory. He explains that, when he was younger, he made a Facebook page, and managed to get 3 million followers within 3 hours. Scientists kidnapped him and Kelly and did experiments to see how their powers work. The two then fell in love and gave birth to the New Kid. They had to run away, moving from town to town, until they got to South Park. After telling the New Kids and the Coon this, they feel better and decide to live happily. After The Freedom Pals go back in time to stop the rise of Mitch Conner, The New Kid encounters their past self in the toilet, just like in the first day. The actions of Kelly are just like they were on the first day.
The New Kid, The Coon and Mitch Conner go back in time so the New Kid can stop themselves from ever seeing their parents engaging in sexual activities, they accomplish their goals and Chris and Kelly tell their child about their backstory:
Chris made a Facebook account and he already obtained a lot of followers upon joining, whereas Kelly uploaded her first Instagram picture and got five thousand followers. Their powers didn't go unnoticed, and government agents kidnapped both of them and made experiments with them in order to find out their power source. They both met in the government's laboratory and fell in love with each other, giving birth to the New Kid, who obtained a million followers upon being born. After that, the three of them escaped to prevent the New Kid from being used as a rat lab and moved from town to town in hopes of living a normal life, to accomplish this, Chris and Kelly started to put special medicine on The New Kid's dinner in hopes that it would control their powers, but the only thing it did was giving him powerful and smelly farts. After telling the truth to their child, Chris and Kelly start to feel better and they decide to lay off the marijuana and wine respectively.
Back to present day, Chris and Kelly love each other again and are glad that the three of them decided to choose South Park is a place to live, in fact, they are both so in love with each other that they decide to leave their child alone and go to their bedroom to have sex, much to the New Kid's shock, to which Professor Chaos tells him that "no matter how much [they] try to change things, [their] father will have always fucked [their] mother."
在真理之杖中，两人是相当恩爱的夫妇，但在完整破碎，两人出现了吵架的现象。 When Mr. Mackey speaks to Kelly for clarification about the New Kid's sexual orientation, Chris berates her, worried people will find out the truth. This then continues until they argue all the time. Even in The Many Asses of Dr. Mephesto when The New Kid has to make a decision of who to kill, the two yell at each other from across the room and try to persuade the New Kid to kill the other one. When they tell him the truth, the two feel better and make up with each other.
