The person in the shower had the shape of a female and Jon just knew how someone like that would react to this situation. And sure enough, it happened.
She screamed. "What are you doing in here?! Who are you?!" she yelled at him, as she stumbled out of the shower, grabbing a towel on her way out. "How did you get in my house?!"
Jon tried his best to calm her down. Obviously, whatever caused Biff to show up, caused this woman to do the same. "Listen, I know this will seem strange. But you've just teleported into my house."
"What are you talking about?! This is my house!" the woman screamed.
"You're wrong," Jon said. "This is ..." But when he looked around the bathroom, he realized that the woman was right. This wasn't the bathroom he entered a few minutes ago. It was completely different. The woman didn't teleport. He did.
The woman secured the towel around her body, then reached for the door. "I'm calling the police."
"No. Wait," Jon said.
But she didn't.
"Oh, man. Now I'm really in trouble," Jon said to himself. If only he had the stone with him, he could make all of this go away.
He looked around for a towel and found one. Then he wrapped it around his waist and followed the woman out the door.
