"Like the Operative, like Mal himself, Simon has been forced to give up everything, every single thing, to protect his sister. And like the Operative and Mal, he’s hardened around this mission with a scary single-mindedness. It’s not that he doesn’t love her, he does, but there’s an extra layer of it now being his Entire Purpose that has given him incredible blind spots w/r/t [with regard to] emotional outbursts about it. The thing is that Simon can’t ask the question Mal keeps asking, which is: is this worth it? If Mal loses two more members of his crew, well, there are still four people left to live for, and his ship. If Simon even considered dumping River, he’d die."
