A collection of Half-Life and Portal drabbles, some for the r/fanfiction Discord Drabble Night, some for other challenges and prompts. (The genres only really describe the first one, since there's a lot of variety, although I guess they're all "sci-fi" to some extent).

He held the last page of the script up in both of his hands, pinching the center of the top edge, one hand tilted to the right, one tilted to the left, one twitch of the hand away from tearing the sheet in two. "Tell me… Miss. Chell… do you wish to die?" - The "G-Man is God in disguise" theory is used here.
