Rodney McKay is newly Divorced, and extremely wealthy, despite having had to force his now Ex Wife to take a settlement. The Marriage hasn't exactly ended badly, he doesn't quite know how he managed to snare Samantha Carter in the first place, it must just have been circumstance, but they're not close, and he's not sure that they ever were. Rodney is very high profile, having long ago abandoned the environment of a Lab, for an Office, and a portfolio of Government Contracts. That profile also puts him in a lot of danger, and he's been advised to hire a Bodyguard. He actually interviews several people, but what seemed like a good idea in his head, namely getting a hot, tall, blonde, female bodyguard, really doesn't sit too well with him in person. He never thought he'd say this, but his "type", just doesn't work for him anymore it's been spoiled for him, because it's as bad as if Sam were in the room, and what he actually ends up with is an Ex Air Force Major, called John Sheppard.
