If John Krasinski sacrificed himself in the first movie, it would be appropriate if Emily Blunt sacrificed herself in this movie and the offspring continues the struggle in further movies
shareShe can still have children plus raise the child that is there also.
shareSigourney Weaver didn't die in the 2nd Alien movie and Linda Hamilton didn't die in the 2nd Terminator movie, so Emily Blunt cannot die in the 2nd Quiet Place movie, more likely she'll die in the 3rd movie.
shareWould've been a bit formulaic/predictable, don't you think? What happens in the third movie, the deaf girl dies, then the kid in the 4th, then the baby in the 5th?
