"You didn't answer my question!" Darcy doesn't stamp her foot, but the extra emphasis on the last syllable really implies it. "Can you find her?"

It's a struggle to tear her eyes away from Severus after she makes her demands, and pay attention to her communicator so she can forward that message on to Claire, but she manages. The effort it takes, however minimal it is at her level of technological experience, helps to force her to slow down and calm herself a bit. She takes a deep breath, and once she's sent the message on to Claire (yes, they've met), looks sheepish as she turns her attention back to the wizard whose help she's seeking.

"Look at me. There is a reason I'm on Comms and not on one of the teams out there. I am the last person someone would come to for help." So she says. "If she's asking me, it's because something's gone seriously wrong, and she must have exhausted all other options." Certainly it isn't because she's a friend, or resourceful or anything like that.
