Specter, here. I'm here to clear some things up. Some of you are concerned the Slender Man Division of the Paranormal Termination Consortium is out to get you. Short answer: No. Long answer: No, you fucking idiots. We're all on the same team here.
Nonetheless, it is quite clear that Nightcrawler's unit requires additional oversight. He has managed to keep his clearly-homicidal tendencies contained for now. No Runners have died, yet. As a matter of fact, they've simply been tracking them down and giving them a safe place to stay under heavy guard. They have engaged Indoctrinated recently, and killed at least one 'Revenant.' Our first encounter with one resulted in the death of a P.T.C. soldier, so we know how to deal with them and avoid such incidents in the future.
Now, as for this incident with B2.
The bastard is insane. Before his disappearance, he was spouting something about how he was 'lost on two paths.' He's also taken his equipment, so if nothing else, we need to track him down and take it back. Normally, we have great mental health coverage for our soldiers. And for good reason. But, B2 will most certainly not be getting any such treatment. He's beyond help. Best thing we can do is kill him, for his own good.
If you see anyone toting around a high-powered sniper rifle, wearing a gas mask, or wearing a military combat suit, please avoid him at all costs.
