Mycroft, though well-versed in mandatory meet-and-greets, has never been fond of them. They're useful for gathering information and observing people he may otherwise not have much contact with, but they're also crowded and noisy and have far too much easy-access finger food. He'll need to wind down quite a bit after this.

Once he's applied the hateful name tag to his lapel, he decides he'll make the most of his time by talking to someone he's taken a lingering interest in since being hired on at Hellsing. There is obviously much more to the resident groundskeeper than his title would imply, and the more Mycroft knows about the power structure of Hellsing, the more capable he'll be of using its resources to everyone's best advantage (including his own).

"Mr LeMat," he says, approaching Sebastian with a polite smile. "I don't believe we've properly met."
