This section also deals a lot with the idea of change. After Tim is shot he is being cared for by Rat Kiley. After moving on to the later recovery process, he returns to find that Rat too has been wounded and was shipped off, only to be replaced by Bobby Jorgensen. This being a big change in his already unstable life it creates a major imbalance inside O'Brien, not seen in the previous pages of the novel. While change can be a huge hurdle in many lives, one cannot shake the fact that change is inevitable and is needed to move forward in our lives.
