He thought about it for a moment, and decided to leave it. Having a brother named Emily was certainly something unique, and at the same time, he did just want Emily to be a boy; Never anything about acting different.
So he decided to leave it as it currently is. Emily was male, but still acted entirely like a girl, and still had the same memories; There wouldn't be any notable change for a few years, and Jeff found the thought a little cute. Plus, it's not like things could change on their own.
The former girl was watching cartoons, seeming to enjoy them despite being a little old. He saw that Emily was still wearing a skirt, and a thought briefly crossed his mind on if it changed his underwear, but Jeff pushed that aside, being a weird thing to think about. "Why would it even matter if it did..?"
He didn't really want to think on his sibling's underwear, let alone some of the other private things that he couldn't tell if they were changed or not. He minimized out of the chronivac for now, and went over to his former sister.
"Hey, Emily." He stood not far from the couch, focused on the now-boy. "Hi Jeff!" The voice definitely would need some getting used to; Emily's voice was a lower pitch, but not too much lower; Just enough to be noticeable.
"So how are you doing?" "I'm doing great, hehe!" The giggle was definitely a bit off, and he'd need to get used to it. "Alright, that's good to hear. Just wanted to check in."
Jeff definitely was going to need time to readjust to this new situation... He decided to return to his room and look at the Chronivac more, while Emily got off the couch to do his own things.
