Jack straight up treads on Ryan's hand to show how much he doesn't give a shit (plot twist: he does).

He does a rote glance about for splicers as they leave the office, but the hallway and the rooms beneath it are silent. Nobody's there to interrupt them as they make their way to the control panel for the moment of truth.

A glance at the paper, and then Jack taps the number into the control panel, not expecting very much.

And then the whole wall begins to move.
