Not sure how I forgot to read this one. It was pretty grim, but positive in the end. I like how Rush and Ben have evolved as a couple. Clay's story was heartbreaking but he seems like a great character. I didn't realize he was native American until the very end, though; that was slightly disconcerting.
One relatively minor point: Hepatitis A is spread through fecal-oral exposure (contaminated food or poor hand hygiene), so isn't generally considered a sexually transmitted infection (although it can be spread through rimming); it isn't typically tested for in sexual assault cases. You might consider changing it to hepatitis B, which has the same mechanisms of transmission as HIV. Hepatitis C does, too, but B would be more likely.
