OK Carlotta, but you can't add events to the story (such as A sneeking in and killing B, as much as I like that idea). If you do, then it's changing the story, and as much fun as that might be, the discussion will get quite weird, quite fast, and I don't think that will accomplich much.
All we have to work with are the events in the story, and the only question is what should the prisoner in cell "A" do? His only options are to stay put, swap cells and a third one that it does not matter. What shall it be?
I take it you are in the "does not matter" camp.
ubntubnt, Same thing. No adding events to the story, It's all about whats the best course of action for the man in "A". Stay, switch or that it does not matter.
Just over 21 hours to go.
