The first time I had a sim killed by a meteor was before Seasons was released. I know this because my sims, 3 YA female housemates, were in their back yard gardening when a meteor hit them. If it had been after Seasons they'd have had some sort of a greenhouse.
I only recall one of them being killed and she happened to have a death flower in her inventory. At that point I had no clue what a death flower was for and was stunned when she knelt and offered her flower to Grim and he let her live. So it was a learning experience in more ways than one for me that day. Since then I've taken a whole new interest in death flowers. Most of my sims carry at least one in their inventory now.
