"can't imagine there is anything my brother would say about me that would cause me to smugly stand by, knowing I could save his life."

How, exactly, do you know she's "smug"?

How, exactly, do you know she's "smug"? Because she said she would donate the marrow and then reneged without the courtesy of explaining why. When given the opportunity to explain what appears to the casual observer to be an uncaring decision, she chooses not to. That, IMO, is smug.
