Experiment: "Lucky" (Inanimate Insanity)

Fan gets sick, like really sick. And Testtube is worried. While she tries to find some sort of solution, she just can't. She has one chance to save Fan, though at the expense of Lightbulb and Paintbrush. She makes a choice but was it the right one?

One of those "Testtube runs experiments on her friends" aus. This is also a human au.

There will be ships in this, or at least implied ships.

TW for terminal illness, experiments, torture, kidnapping, needles, nightmare sequences, body horror, and other stuff I'll add if and when it shows up
