I will hit myself for not being able to find this on my own.
Jared is an awesome infectious disease researcher in a level 4 [5?] biolab.
Some kind of disease outbreak happens and he is called in to Oregon? Washington State? to deal with it.
He and Jensen had a relationship but it went to pot. Jensen is also an infectious disease guy but he moved away to work in Africa? India? after he and Jared had a big outs type argument. Maybe Jared cheated? Or he might have screwed Jensen over career-wise? Maybe I'm mixing stories.
Anyway, Jared figures out he needs Jensen's help to stop this from spreading and to help make a cure. The military gets Jensen, who is none too pleased. But the disease is spreading [a city in Germany reports cases and they level it to the ground to stop the spread of infection?] and Jensen is interested in helping, so he gets over being pissed at Jared.
Jensen figures out something about using an RNA type treatment or something and tests it.
Jared is worried. Everyone figures out everyone else still has "feelings" and ENDING.
I don't think it was a crossover or fusion with Outbreak, but it was similar...ish.
this fic is a few years old at this point.
Does that sound at all comprehensible? Or familiar?
I can't remember the title, the author, anything. I know I will be so irritated when someone says what it is.
Anyway, your help is very much appreciated.
