This standalone story gives the reader a glimpse into the workings of Midnighter's tactical talents. Midnighter can predict all possible outcomes of a battle before the first punch is thrown; some say he chooses the outcome he wants, then works backwards through the fight to see how to achieve it. This issue shows that process, starting with the end and working backwards to the beginning.
The title is a French phrase indicating something already accomplished, before those affected by it are in a position to question it; a done deal. Here, the outcome of Midnighter's battle is the fait accompli, and there is nothing his opponents can do to prevent it.
