Amethyst
There was no time to waste. Each millisecond spent dillydallying would be another millisecond Steven was stuck on Homeworld. No time to eat, sleep, breathe— no point doing those anyway.
There was no time to waste. There was only the task at hand— hold this, carry that; give Peridot the wrench, hand Pearl the screwdriver; scavenge Injectors for parts, find solder wire and tungsten…
There was no time to waste, not even for rest. She wouldn't, couldn't, shouldn't stop working.
No, she refused to stop.
Because she'd only end up crying, and they had no time to waste for tears.
