A long-standing partner? It might be a little late to introduce him as a long-standing partner, simply because it's been months in story time and he hasn't come up - a co-worker perhaps, unless he's been recently assigned to her as a partner.

And I don't know, how about we just mull it over for a bit, the organized crime or counter-terrorism bit? I'm not necessarily big on having to have every single plot element hammered out before it even happens. Sometimes I just like that touch of the unexpected, the spontaneity that comes along during the writing if you know what I mean.
