 Well, two answers to your question. First of all, there's plenty of supplies on board the International Space Station. They keep the food, the clothing, all of those sorts of things stocked up on the lab just in case something like this happens. So plenty of margin there, no issue. Now, you're right. They could, in theory, bring the two crew members home on a SpaceX Crew Dragon. It would take a lot of replanting. It'd be a big deal if they did that. And it would mean they concluded that the Starliner wasn't safe to come home in.
