How do I write an original scene based on 1984 by George Orwell? It has to be 1500-2000 words and be a scene about a minor character in the story....

1984 is a great choice for this assignment because it gives you license to be very creative if you so choose. How close do you want to stick to the actual storyline, and how dark do you want it to be?

You could write about O'Brien, who knowingly lures Winston and Julia into betraying Oceania. Is he a harsh, scheming character with no heart? Did something happen to make him into the person he is?...

You could write about O'Brien, who knowingly lures Winston and Julia into betraying Oceania. Is he a harsh, scheming character with no heart? Did something happen to make him into the person he is? Or maybe you could turn him into a triple agent: he actually is trying to bring down Big Brother but had to give up Winston and Julia to do so.

What about Winston's former wife, Katharine? Their story is told entirely by Winston, who by his own admission wanted to push her from a great height—perhaps she is a great deal more complex than he gives her credit for. 

You could write about Goldstein, who is a nebulous figure. Is he real or a figurehead? If he's real, you could write his story. If he's not, you could write the story of how he was created. (This could also work for Big Brother.)

Finally, there's a scene in which Winston hears a prole woman outside his apartment with Julia. You could tell her story from that day, how she saw a man looking out the window, or the story of the proles.
