"Problem there," I said, "is you didn't keep track of them. The name Lauren Carmichael mean anything to you?" He shook his head, brow furrowed. "No. Should it?" "There weren't two tunnels. There were three. She found the third on a dig in Nepal. Your boys showed up to save the day. See, first they pushed Lauren into slaughtering all the witnesses, except for one." Bob blinked. "I...didn't intend for them to hurt anyone. That wasn't the idea at all." "Second, instead of taking Lauren out, they pretended they were on her side and spent the next two decades trying to con her into triggering the apocalypse. You said it yourself, Doc: they're creatures of entropy from a dead world. Did it occur to you, even for a second, that they might not stop at the end of your leash? That they might maybe, just maybe, want to turn this planet into a lump of charcoal so it'd feel more like home?" He didn't have to answer. The shame on his face told me everything I needed to know."
