When they got home, Zoe reached up and deposited Jon's head on her original, now-armless body and walked off. "Hey! Wait! Zoe!!" His yells were ignored, or maybe not heard, as she went upstairs. He just stood there, trying not to lose his balance or fall. With no arms, it would be difficult getting back up. After a moment he plopped down onto the couch, watching what was on TV. Transformers.
Jon kept getting the feeling of moving, and it was disorienting to realize his arms hadn't actually moved at all. It was even stranger than the foreign feeling of his sister's body in her Goth clothes, her breasts and what was probably his mother's vagina. Mikey walked by in Jon's body, or at least the half of it that was his, several times, seemingly gloating.
After a while, Zoe came back around and gave him one of her sets of arms; Mikey's, with her hands on the end. "Sorry, Jon, I completely forgot I had four arms. Mom took his arms away as a punishment, at first. Y'know, like she used to do to us. Then she just forgot to give them back."
Jon just shrugged, and was very happy that he could now. Maybe now he'd get some peace, albeit with Zoe's body and Mikey's arms.
