Talk:Who's In The Box?/@comment-4901236-20131215145302/@comment-24004040-20131215153600

But "B" in the box means there is somone in there. We saw Black Widow in S4, so she can't be in that box, can she?

B probably really just means "body", because it's to obvious and people don't even think of that. Or something like "betrayer", because whoever is in there, we didn't see this person, but that person seems to be important plot wise, because otherwise they would reveal way sooner who is in there.
