Dairine's gone looking for Joan. It's computer-related mostly, though that's not the only reason; she meant to give her one of the other two Musketeers but couldn't quite bring herself to, which meant building a new laptop out of all the parts she's collected over time. Which was nice, as projects go; sensible and uncomplicated and easy the way it seems like nothing is.

The point is, she's been looking for Joan. And after a while, she finds her.
