Following with her group, Rio had ended up meeting with another portion of the group from Orpheus.  She then followed, quietly, them to this new residence which was serving as an impromptu command center...for now, anyway.  Apparently there were still some of them out there, and they all needed to regroup so that they could all sit down and plan their next move.  For now, it looked like everyone was splitting up inside the mansion, so...she took the opportunity to go exploring the big house.
