You were Harry Potter's older sister named Rosalind Potter, you were 17 years older like the Weasley Twins. You, Hermione, Harry and Ron wanted to join Dumbledore's army but you needed a New Defense Against The Dark Arts Professor because Umbridge was.. useless and wanted power.

Right now you and the trio walked in Hogsmeade and enter the Boar's Head, You, the trio and the others Gryffindor and Ravenclaw were in a room and Hermione stand up to speak.

"Uhm... Hi.. You all know why we're here.. We need a teacher.. Proper teacher.."

It was awkward as Hermione speak while everyone were sitting, you sat next to Harry.

"One who has really experience to founding themself against the Dark Arts."

Hermione said and a boy Gryffindor then spoke, a little too harshly in Ron's opinion.

"Why?"

The Gryffindor boy said as Ron raise a brow.

"Why? Cause You-Know-Who is back."

Ron retort as the boy said.

"So he says-"

The boy start but Hermione correct him.

"So Dumbledore says."

Hermione corrected the boy that hold back a huff.

"So Dumbledore says, because he says. The point is, where's the proof?"

The Gryffindor boy said as everyone look at him, Fred was fidgeting with his fingers next to George.

"Maybe Potter could tell us more about how Diggory got k!lled."

A Ravenclaw sitting next to Ginny said, Harry said he didn't want to talk about Cedric and whisper to you that he wanted to leave but then.

"Is it true you can produce Patronus Charm?"

Luna Love-good said as everyone look at Harry, Hermione confirmed it and Dean Thomas said that he didn't know Harry could do that, Neville said Harry k!lled a basilisk one Time and Ron saying that he fighted Dementors, blah blah blah. Harry did his speech.

As you were listening, staying silent as you lean on a table, there was students starting to look at you, why don't you be the new teacher? You're capable of it.
