Author's Note: I've wanted to write a little something about Elsa, Anna and Kristoff being in Hogwarts and didn't know how to put it until Anon poked at me on Tumblr. There we go!
"Tell me, Minerva, have you heard about the Arendelle sisters?"
She looked at the new teacher behind her glasses. "Do you mean it in the good or the bad way? And of course I have, the elder is in 7th year now."
"Well, I figured out that as you're the headmistress now…"
"You seem to forget that I have eyes everywhere. And being able to turn into a cat helps a lot to spot the mischiefs that the younger does in the corridors at night with the other 4th years."
He seemed relieved that she got on the subject on her own. "Oh, so there are bad things about them. I see. Because I heard at the table of professors that miss Arendelle was a pain in the… Well, you know, but I can't understand how it's possible when I see how her sister behaves…"
McGonagall had to restrain a chuckle.
"You'll quickly learn that they are verydifferent."
She twirled her wand and the pile of books that was floating next to her went ahead of them in the corridor to go to the library on their own. When she tugged back her want in her sleeve, the movement made her realize she better clarified what she had said.
"Actually, that difference is their strength. Anna tend to get distracted in class, and often is talking and getting excited – too excited, if I recount the times she exploded cauldrons during Potions – but this hyperactivity is exactly why the Gryffindor Quidditch team hasn't been hit by any bludger in a really long time."
The man smiled and nodded. He remembered the spectacular performance of the team during the last match, especially McGonagall's reaction when her house won.
"So she's the opposite to her sister, then. Elsa's attitude in class is remarkable, and she has perfect notes."
"In yours, yes. I don't have the same echoes from other teachers."
He frowned, but didn't want to contradict her.
"They have lost their parents at a young age, you see… Elsa had to take care of Anna quite quickly and with no preparation. And Hogwarts is a like a home to them."
"They're really that complementary?" Asked the man with wide eyes.
McGonagall smiled.
"You should ask Flitwick, he's in charge of the Ravenclaws and will be the first to say that the contrast between the two is astonishing."
"I suppose they bond a lot anyway."
"Yes, they do. On spare time, when the tables in the Great Hall have no sorting purpose, they always work together on the same bench. And there again, the classes they excel in are the weakness of the other. They help each other a lot."
The new teacher frowned.
"Not to be offensive, but… There are subjects where Anna is good at?"
"This is offensive, sir."
"I'm so sorry, I…"
She was right, though he noticed that she also said that because she was a Gryffindor and she took it personally. Her eyes were piercing his.
"She has excellent grades in Defense Against the Dark Arts. She's notably better than Elsa on that point. And she has more fun in Potions class than Elsa does, probably because the latter gets easily scared of being dangerous with what she creates. A situation I also heard of from the Charms teacher."
The man nodded. McGonagall kept walking, continuing.
"But on the opposite, Elsa helps her in Astronomy, a subject in which Anna reallylacks patience…" added the headmistress with a sigh, "And she helps her in History of Magic and Care of Magical Creatures."
"I see…" Understood the new teacher, and he took mental notes of all of this.
"And finally, Anna is really good at Transfiguration since her 1st year." Said McGonagall with some nostalgia, picturing memories of young Anna in her mind. "Though she has been a little inattentive lately. I suppose it's because it's the first time that Gryffindors have this class with Hufflepuffs and that she met Mr Bjorgman. Her blush matches her hair every single time they sit nearby."
They both laughed softly.
"They're still teenagers. Elsa's maturity can't do much about that…"
"Actually, I think that she would never dare to come in the way of her little sister's happiness. That's all she wants, after all. For her sister to be happy. I've noticed that she had trouble to hide her joy when Gryffindor won the match against Ravenclaw."
"Well, thank you for all that information."
McGonagall simply nodded, her glasses glistening with the reflection of the torches in the corridor.
"May I know why you asked me about the Arendelle sisters in the first place?"
The man passed a hand behind his head and had a nervous laugh.
"Uhm, Miss Arendelle broke an armor of the 5th floor this afternoon."
McGonagall groaned silently. "Again?"
"Do I need to precise which Miss Arendelle I'm talking about?"
"I don't think that it's necessary."
