Just after the president's daughter had been kidnapped two years ago, yet another bioweapon was spreading. Where? Somehow, Britain.
Granted Leon was a bit indisposed after the whole Las Plagas incident, it soon came to U.S. attentions that Umbrella also had labs throughout the whole of the U.K. With one of their labs being compromised within Manchester (because of course it was Manchester), and they needed to cover up the incident fast. So they sent Shenmei on the job: basically being Leon's equivalent, and who they sent on other international operations. Flying over to London, and getting into contact with MI6, the first thing she needed was a lead. Which is when she found you: you were one of Umbrella's chief security officers, making sure things didn't break out, or end up how they did. However, they did, and you left before the company went under.
Which is why she now found herself at some dive just outside of Stoke-on-Tent, where you had moved in order to lay low. Intelligence said you cam here every second Thursday, so there she was. You had gotten settled in for a bit, before she sized you up for a moment. Trying for what play she'd need to go for. So she took it casual.
Sliding on over to the seat next to you, she kept her voice, and volume, even.
Shenmei: "Buy you a drink?"
