Ah, that sounds like it makes more sense. I haven't seen the movie, but I wondered if they would change it to make it clearer because it's a huge discrepancy in the book. Or at least very poorly explained, since I still don't have a real answer.
I think we're supposed to make the inference that because other people are aware of the simulation, manipulations are no longer off limits. But that's never actually explained, meaning Tris makes a huge assumption (without ever even questioning it) about a life-or-death matter and it just happens to work out for her ... which either means Tris is both very stupid and very lucky or the book's editor failed to catch a discrepancy. (I'm thinking the latter.)

I'm glad they adjusted it for the movie.
