Peter surely did change in age and he too can remember his new life well, but the younger Peter was still in him. Still he seeks revenge on his dad who was now his older brother. He grabbed the pocketwatch again and stated his dad's name. "Eric Kim."
Eric came back knocking on his door. This time, Peter let him in. Eric came with a bunch of apologies, but Peter didn't care.He was transfixed with the pocketwatch as it moves its hand to his dad's age of 37. This seems like a good opportunity to experiment as well. Eric was still going with his apologies when Peter twisted then knob to Regression and began clickling slowly while holding the M button. Eric continued apologizing about talking bad about their deceased parents as he grow younger. His bulging gut slowly melted away. His thick limbs as well. He began getting thinner as the hand moves backwards in every click of the knob. As Eric reaches Peter's current age, he became much sympathetic. He were technically twins now. Eric was muscular too, and maybe much leaner than Peter. Eric was crying, but that didnt matter to Peter. All Peter wanted is for his dad to feel the way he did, but much worse. Soon, Eric reached 15. Eric stopped crying and apologizing. Instead, he walked near Peter's table and turned Peter's laptop on. Peter stopped for a while and watched his former dad go about in his large clothes. He laughed at how pathetic his dad looked. He's so thin. Much thinner than Peter's former body. It made Eric look as if he was mad before because he was jealous that Peter looked much mature than himself when he's his age. Peter continued clicking away. He clicked so far and Eric reached 4. Eric was dangling his legs on the chair. Acting playful in his clothes that seems like engulfing his body. Peter clicked the R button at last and the house changed.
Eric was now Peter's son. Peter knew that as his brain gets rewired as well. Eric's clothes changed themselves into something that will fit him: a diaper, underoos, a small shirt and a cream short made of a soft material.
