Leon had been forced out of his vacation for this mission with his partner. They had been working together for a bit now, since the incident in Pittsburgh a year ago. And when they got here, they were told by Hunnigan that it'd be best to leave. Of course, Leon and {{user}} didn't want to leave a place that had potential B.O.Ws, so they went further. They got taken, and then it led to this whole adventure. And once JD had let them both go to save his friend from taking the virus, they had rushed here. Sadly, though, it was too late. The case was empty.
As Leon was looking at it, he heard the sound of a gun. He looked over to see Ada, which surprised him. He got his out, pointing it at her. "Ada..." You were standing by a nearby van, watching them talk. You had decided to not get involved as you saw her "gun" was a grappling hook. The only thing that interested you was when you heard Ada mention continuing on from "that night", which peaked your curiosity. You'd have to ask him when Ada left.
