Frisk falls, and catches themself on their hands and knees. Behind them, they hear Lapis scream. Sans is there before they can turn to look for him, and they wipe mud on their pants as they rise.

She's really not looking good. Frisk cringes a little, guilt stabbing at them even though this wasn't really their fault. They don't know much more about what kills a Gem than Sans does - though they do figure it's not the same as a human. Their bodies are different, after all. A human probably would have been a lot more hurt by now. (A monster would have died a long time ago.) Gems have to be pretty tough.

Still, they reach out to tug at Sans's sleeve when the blasters reappear. She's hurt already, bad enough not to stand back up. They don't need to do all that.
