Let's put our three chunks together and see what we've got.
Here's the original snippet:
"Accursed creator! Why did you form a monster so hideous that even you turned from me in disgust? God, in pity, made man beautiful and alluring, after his own image; but my form is a filthy type of yours, more horrid even from the very resemblance. Satan had his companions, fellow devils, to admire and encourage him, but I am solitary and abhorred."
Here are our worked examples with all three chunks combined:
“Muuuum! Why did you clean my room so now I can’t find my charger? Diamond’s room is just a pile of clothes and food, with literal rats in it; but my room is now like this weird clinical fantasy of yours, and all my stuff is gone. In prison the guards have to give you notice when they’re going to come in and inspect your room, but you turn my room upside down whenever you want.”
"You stupid Redditors! Why did you spam my address into space so that now I’ve been abducted by Gammalorians? You’re all sitting in your gaming chairs safe at home, with sweet lighting and surround sound; but I’m in a gelatinous pod somewhere past the Oort Cloud. When you swat a rando on the internet, at least their door gets kicked in by humans, but I’m getting probed by a bunch of four-fingered blob monsters."
And here are your fragments combined into one text box. How well does it hang together?
So that's our structural draft!
Next, let's see if we can capture some of Shelley's 19th century Gothic Romantic intensity.
