[I2S1] DD: Call one of your people.
You ring up CD to ask why he hasn't been responding to your backup requests for the past 15 minutes.
Seems like he can't hear you, for some oddball reason or other. You can probably take an educated guess as to why, but you never cared to keep up with the intricate details of the rest of the gang's inventory. You're not their nanny.
Can't assume that he's dead, he would have made a show of it. With Bones on scout detail and Sharper doing who knows what, you're stuck on your own. At least until you're inevitably found.
