Seemingly all on its own, the door David ducked through swings shut lazily. A soft click follows, easily missable under the sound of voices as Umeni approaches, then a gentle, hi-pitched whine as Aiden launches a small scale DDoS attack on the system, flooding it with information until it doesn't know up from down, open from closed. The door David came through won't open from either direction, now, at least not for a few minutes, so neither he nor Umeni will be going that way.

Where one door closes, another opens, however, and so Aiden opens two -- one for Umeni, to herd them away from David and back towards Wrench, and the other for David, himself, to try and get him where he wants him.
