Also docked to the space station is SpaceX’s Crew Dragon capsule that ferried four astronauts to the ISS in March, and a Russian Soyuz capsule that delivered three others in September. Stich acknowledged that at least one of those vehicles could provide an alternative ride home for Wilmore and Williams.
Pretty sure Soyuz can be sent up empty if needed
It can, they did it last year, but generally any empty seats going to or from the station represent a big waste.
