Dayo waves back, and takes a seat at a table where some people are ignoring her.

Hopefully Dayo knows what she's doing.

She probably does. She starts talking to a couple of girls.

Dorea will likewise resume intrahouse socialization.

Soon enough they're done eating and the Gryffindors go to class.

"I heard the teacher is a ghost," Neville whispers.

"Is that normal?"

"I think he's the only ghost Professor...They say he just one day walked out of his office and never noticed he'd left his body behind."

"That seems an odd thing to miss."

They need to ask the paintings for directions twice but eventually arrive at the auditorium-like classroom whose walls are covered by books.

Oooh!

After they've settled in the whole class gasps as a short, hunchbacked, old ghost walks through the wall and takes a seat.

Spoooooky.

So spooky.

Professor Binns starts his lesson. ...he seems to be an experiment designed to make even the coolest magical revolutions sound mind-numbingly dull.

...Wow.

Well, okay, if she ignores him and just reads about it in the textbook, will he notice?

Nope. He seems oblivious to the classroom, actually.

Magic school isn't perfect, it seems.

Thus proceeds their first class, and most other kids are drooping or asleep by the time it ends. Homework is five inches on whatever boring topic they covered today, which elicits a collective groan.

Five inches? Weird way to measure, but okay. Well, if no one else was ignoring him and reading the textbook she supposes she has an advantage.

Probably.

Then break!

Hmm.

How discreetly can she investigate the forbidden corridor?

Depends on who she tells about it. If it's "no one" then pretty discreetly.

Yeah she just wanted to be sure no one was following her or anything.

No one's following her!

But when she gets there she runs into someone who looks like he hasn't had a happy day in his life. "And what are you doing here?"

Well.

"I'm sorry, sir," she says meekly. "I got lost, I was looking for the way back to the common room..."

"Lost, I'm sure!" he says, limping towards her. "You're gonna be coming with me."
