Marsha gave the Professor a smile as he said that she had done a good job of thinking about their boundaries. She guessed that that was what she had been trying to say… Yes. That. Hehe.

Oh man, his otter had gone. Saddd face.

Oh. Patronuses?

Frown. She knew that she couldn’t wait to find out what her own was; her Mum and Tad often used them to send each other messages if her Tad was working away from home for a while. Hmm. ”They are hard to make … uh… corporeal?!” Was that the word? Was she even thinking of the right thing? Was that the same thing as the Professor’s otter? Or was a patronus something else and she was being an idiot?

… She was pretty sure that she was on the right track. Hopefully.
