The next place Jon checked was Mikey's bedroom. If Zoe had Mikey's personality now, then whose did Mikey have?
When Jon entered his room, he realized that Mikey wasn't there. But given how his bedroom now looked, Jon was fairly sure that his little brother now had his dad's personality. Posters of anime characters were replaced with framed paintings. His toy spaceships that were previously kept on his shelves were replaced by books. And there was now a desk, with a computer and lamp sitting atop it. It was almost like walking into a library or a study.
Jon only had a tiny bit of curiosity as to where his brother was. Mostly, though, he couldn't give a fuck. All he cared about was getting his stone back.
He left the bedroom and walked downstairs.
