Sarah takes diligent notes and then tries to transfigure the match. After a bunch of attempts she tries something a little different and ends up with a wooden needle near the end of class.

Which is an interesting way to fail and earns her an actual smile.

She smiles back and then keeps trying. She doesn't make any visible progress by the end of class.

She gets five points for being the only one to go as far as that and class is dismissed. With homework.

She writes down the homework then packs up and makes her way to the library. She might as well get a start on her homework.

Homework is to keep practising turning a match into a needle but the result the Professor's expecting by next class is only slightly better than what she already got. Charms homework involves writing stuff, though, and no practising because they might set stuff on fire.

She'll look up anything she needs to for the Charms homework and start writing. Practicing Transfiguration can wait a bit, she'll go back to the common room if there's still time before dinner.

There is time for that, yes!

She'll put her bag away in her room. Is there anyone she knows in the common room? Or anyone she ought to know like the boys in her year?

There are a few older years, reading or studying, and a couple of boys her year sitting on the sofas and having a heated but hushed argument about something.

She walks a bit closer and tries to hear.

"—it's obviously the first wand that counts, that makes no sense!"

    "Of course not, if you change later then your wand will change too."

"Yeah but they picked two woods that are pretty much the same one with that one detail changed—"

    "People don't change that much!"

That doesn't sound like a conversation she can contribute to. She browses the shelves to see if there's a transfiguration book at her level.

There is! There are several, actually, this is a good complement to the library.

Sarah finds a seat and reads while keeping half an eye on the door.

No one walks in. Eventually the two boys reach a resolution and leave.

And then it's dinnertime.

She puts away her book and goes to dinner.

Familiar people are having dinner!

She'll sit by Mandy if she can find a seat. They got interrupted when Transfiguration started and Mandy might want to ask her about what she said.

Mandy seems to have all but forgotten about it and is chattering to Padma about celebrity gossip.

She'll listen with half an ear. She's not usually interested in that but if it's important to her roommates it would be good to know at least a little.

At one point Dayo goes to the Gryffindor table to talk to Ron.

Sarah smiles when she notices. It's good that she's not the only person ignoring the boundaries of house.

And after a few minutes she flops down next to Sarah. "Hi."

"Hi. Should I introduce you?"
