Jon was astounded when he saw that his room was completely different than it was before. It instead looked like it belonged to someone or by the size of it more than one person, who was very well off financially.
Just to make sure that he wasn't seeing strange things, he stepped out and closed the door before shaking his head. But when he got out into the hallway, he saw that it too had changed into what looked like the hallway of a mansion as it was longer, larger and had more rooms in it.
He then went back into what had to now be his bedroom and decided to continue his exploration there. Opening the large walk in closet, he saw that the people who inhabit this room must be a married couple, an older one at that thanks to some of the clothes that are in there.
He was so stunned by what he was seeing that he didn't even bother to figure out what's going on using the stone.
