Jill wasn't entire sure what was happening. She didn't know why Lissa and Rose were here when she just saw them back at Court. She didn't know why Lissa didn't seem to know who she was or that she was Queen.
All she could conclude was there was some weird time travel or something going on. She knew this place was different, but this was a whole new level.
Or maybe she really had hit her head and this was all a delirium induced hallucination.
Whatever it was, she was standing outside Lissa's dorm room. She made Eddie wait in the lobby, telling him she was getting some notes from a classmate. He believed it because she was new and a little behind on things.
