There's the faintest of smiles at the initial response - yeah, real convincing - but it fades off for the explanation. The duration is spent staring over Clint's shoulder, spinning the pen idly and filing everything down in silence. Small gears in an ever-efficient machine turn, one after the next, two hundred for a new vampire is off. Two people in one night evens out the price, but that alone is strange. Combine with leaving no trail and having years of experience investigating monsters and it all spreads out like code on a screen.

"Two reasonable assumptions. The first is it's someone who changed willingly. The other is your target's got a babysitter. Either way, there's more than two deaths."

And that latter is A Problem. Impressive Clint may be, even Will can admit it's a hard time with vampires past a few centuries. A normal human going alone is much riskier. Especially if a long-ranged specialist goes in expecting a single target when there's a more experienced one running about out of sight.

It's probably a good thing he failed to find his target yesterday. One less avoidable death from abomination. "Sure. I'm in. Any specific area of Ealing or is it hopping territory lines?"
