“Are you all right?”

            “Nothing a bandage and twelve hours in an alcoholic daze wouldn’t cure.” John pointed at one of the doors. “Kathy, that’s their security room. You’re our eyes and ears.”

            “Can do. I’ll spend some time looking at their set up, shall I? Might find a few interesting things.”

            “You do that,” John smirked. “Girls and their toys… Where are the others?”

            “Sweeping through the labs in the two floors below, why?”

            “Because I think it’s better if Ifan doesn’t se this. Come this way.”

            Jack and the Doctor followed him to a large set of double doors. John swiped a pass card through the security lock and pushed one of the doors open.

            “God… no amnesty this time, Doc.”

            “No, Jack.” The Doctor meandered among the vats. “Three, no, four generations before they hit the right sequences.”

            “It looks like Ifan was their first viable outcome,” John said, speaking through gritted teeth.

            “Time Lord DNA is remarkably unstable,” the Doctor said. “It has to do with the artron energy we pick up traveling through the Vortex. Jack…”

            “I want it all gone. All of it. And I want to talk to the… person… who did this.”

            “Sorry, Jack. He tried to get shirty with me and, well, you know me. I did grab his research,” John pulled out a microdrive and offered it to the Doctor. “Take this. I can’t think of a reason why, but you might need it some day. It shouldn’t be on Earth at all.”

            “Could there be other copies?”

            “Not according to Doctor Woolf. This was a very closely held secret. Just him, professor Docherty, and Lady Saxon. All the other research is absolutely as advertised. Helping the sick and the poor, and so on, and so on.”

            “All right. How do we get rid of this… obscenity?”

            “I can help with that.” Kathy’s voice sounded above them. “I’ve been looking at the building schematics. Since Dr. Woolf worked alone there were many pieces of apparatus on remote control.  The security people felt a bit uncomfortable, because Woolf seemed to have been rather haphazard about safety and he worked with very dangerous chemicals. See those canisters on the far wall? Very safe in their powder form but mix with water and… If you gentlemen spread the powder around I’ll turn on the taps at the lab sinks as we’re leaving.”

            “How much time would we have?”

            “Very little, Jack. Once water touches the powder, the building will go in minutes.”
