Rayne was a person that Merida liked a bunch and she always enjoyed spending time with her and talking to her. She was a smart woman too and she appreciated intelligence in a person, perhaps more than what she had appreciated anything else. She hadn't been able to find her in any of the places that she'd usually find her so she decided to look in the astromancy tower. It was a long shot, but she knew that the woman liked astromancy so she could be there. Of course Hogwarts being a rather large castle she could had also kept missing her but... Well worse thing that could happen would be looking up at the night sky from the tower remembering of the days that she'd have to do as much for her class.
She didn't want anything particular with Rayne at the moment, not really. Simply catch up. It had been a while since the last time that they had spoken and she wanted to make sure that the woman was fine. Of course it wasn't long before the end of the school year so everyone was getting good busier but still...
Getting upstairs she did spot some students revising their maps and she smiled to herself remembering sitting where they were sitting now, having an anxious expression similar to their own.
