Did you see the last episode? They got engaged, and they decided that one would leave the service and the other would go to the new assignment. (one was assigned to London, the other to San Diego, I forgot which was which). So they all got together for drinks, and Bud was going to do the coin toss so they would see where they were going. The last scene was the coin in the air.......
So they were going to be together, we just didn't know where. And I guess they are still together....let's hope that someday we hear where.
