Greg becomes Susan's twin permanently

One sunny afternoon, Greg Heffley was in his room preparing himself for his first outing with Holly Hills. As he was about to leave, he heard a sweet voice call out from his mom's room, "Hey Greg sweetie, I need a favor from you before you leave to go see Holly." "Uh okay. What mom?" Greg responded, a little surprisingly, as he stepped into Susan Heffley's room. To his surprise, she was in her full beach attire, carrying her beach hat and purse. "I just need you to help me load Manny into the car real quick and then you can leave. You know how fussy he can be sometimes," Susan requested. "What mom? Really, Manny is so difficult to deal with but fine I'll try," Greg sounded slightly annoyed but agreed to help. However, as he was looking for Manny around the house, his mother sneakily approached him, and before he could realize, she removed his shoes and replaced them with her flip flops. "Ow! Mom! What are you doing? Let me go!" Greg yelled out in surprise. But Susan just reassured him with a smile, "Just hold still Greg honey, it'll be over soon." As his feet began to shrink to match his mother's, Greg could only watch in disbelief. The changes that seemed to start from his feet began to creep upwards, till his head also looked just like Susan's - right from the hairstyle down to her voice. "Mom!-- Wait no! I sound like you?" Greg stammered in utter shock. Things did not stop there, soon his casual attire turned into a matching copy of Susan's outfit. Susan even took off her wedding ring and slipped it onto Greg’s now petite and delicate finger. His memories started to blur and reshape themselves. They started to become Susan's, the memories of her life growing up, of getting married and even of giving birth to him. "Now my purse," Susan interrupted his thoughts, taking off her purse from her shoulder and sliding it onto Greg's. This caused his memories to feminize further, now including visions of Susan's life from her perspective. Her transition didn't stop there, as Susan took off her glasses and placed them on Greg. Greg could feel his memories evolving and changing, until all he could remember was being Susan Heffley. Blinking in confusion, the new Susan instinctively adjusted the glasses on her face as she looked around the room. "What were we talking about again? Where's Greg? Where's Manny? Why am I so confused?" Standing beside her with a satisfied grin, the real Susan answered, "You forgot your purse and your other stuff. You can go now." As Susan watched her twin walk over to the mirror, she subtly smiled at her reflection and admired her outfit. She blinked a couple of times, noticing her eyes sparkling behind the glasses, then went back to her motherly duties, resuming the search for Manny. The new Susan muttered to herself, “Oh thank God I didn't leave without my purse. Now if I could just find Manny. Greg was supposed to help me.” Her voice echoed around the room, still not used to referring to herself in third person. The real Susan had pulled off her plan perfectly, creating a clone to lighten her load. Meanwhile, Greg was trapped in a newfound identity, believing he had always been Susan Heffley, having no memories of ever being Greg.
