... Umm, I'd explain, but I'd need an explanation for that. And since I don't have one, I obviously can't explain.

Warning: Randomness, fireplace pokers (YES!!!!!), Death's granddaughter, and a lot of other stuff.

Disclaimer: I do not own Harry Potter or Discworld. But apparently my Aunt lives fairly close to Terry Pratchett.

Takes place during HBP

Susan was a teacher. She was also the granddaughter of Death, but that's just a minor detail. Before anything else, she was a teacher and we was not going to let anyone, or anything, harm her students if she had anything to say about it.

((just so you all know, this takes place during HBP and Susan is the DADA teacher))

"Girl, you really think you can take me on, with a fireplace poker?" The death eater demanded with a laugh.

"Yes." Susan replied simply, brandishing the poker. The death eater just laughed.

"Prepare to meet death! Avada Kedavra!" The spell hit Susan right in the chest and she fell backwards before she stood right back up.

"Why, that was quite rude." She chastised the very shocked death eater.

"B-b-b-"

"No stuttering! It makes you sound like a blubbering fool and we teachers do not like blubbering fools!"

"But your supposed to be dead! Death is even standing behind you!" The death eater managed to exclaim. Susan turned around and her eyebrows rose a bit at the sight of who was behind her.

"Oh, good evening, Grandfather." She greeted politely.

GOOD EVENING, SUSAN. Dead replied. The death eater was still in shock.

"That spell he cast was supposed to be a killing curse, why didn't it work?" Susan asked.

SIMPLE. YOU CANNOT KILL DEATH, FOR DEATH IS DEATH. Death answered.

"But you're Death. I'm just your granddaughter."

BUT YOU ARE ALSO DEATH AS WELL

"Well, that's rather convenient. Does this mean I can't die?"

PRECISELY. FOR THAT MATTER, YOU HAVE PROBABLY STOPPED AGING AS WELL.

"So that means I'm gonna be like you?"

ONLY WITH SKIN.

"Good point. But this means I'm immortal, doesn't it."Susan said, sounding a little disappointed.

BUT YOU WILL BE THE ULTIMATE HISTORY TEACHER. Death reminded her. Susan cheered up considerably after hearing this.

"You're right! What better a teacher than one who lived through what's being taught!" Susan's eyes gleamed in excitement.

"Umm," The death eater finally managed to get over his shock enough to talk, "What happens now?"

"Well, I could let my grandfather take you, or I could do this." Susan hit him over the head with the poker, knocking him out cold. "Well, that takes care of that." And she went on to knock out even more death eaters with her fireplace poker.

Yeah... I had the idea and I couldn't resist. Now I'm gonna go work on my NejiTen oneshot, (comma).
