Advertisements McNulty "retired", hence the "wake" at the bar at the end. We must assume that he and Beadie live happily ever after. I think it was very telling that he walked away from the bar without being wasted - one of the only times in the 5 years he's done that. It was nice to see Prez again - in a way the last scene with he and Dukwan pretty much said it all with regards to the whole series - Prez going above and beyond to help, at the same time knowing how futile it all was. Other shows might have left that kind of scene out but it was another perfect piece to to a perfect ending.
