A: Not so much. From the person who has the Expendable Crewman, they’d first have to take the Expendable Crewman, clearly, but since they get ALL Beings, they don’t stop there — they take any other Beings that person has in play as well. So really, the Expendable Crewman can only protect you when a single card is being taken. It provides a buffer… but that buffer is only one card deep, as it were.
