Carrie's Death
OK so Henny doesn't question why there's a big can of rat poison next to Carrie's freshly baked donuts?
The most common active ingredients in rat poison are anticoagulants and strychnine. Both would cause a pretty ugly death (bleeding from the mouth/nose/ears, convulsions, expulsion of body fluids from the mouth, etc. She wouldn't just be lying there all put together and peaceful looking. Yes, it's a movie, but come on.
Great balls of fire!...*hiccup*...It's Rhett!
