Ratchet is in his office, replacing diodes in laser scalpels. He examines each through an eyepiece on an arm mounted to his desktop, then touches an iron to loosen the connection to the other components. He grunts as the scalpel he's working on now makes a small fizzle sound, then extends tiny forceps from his fingertip to remove the diode. He carefully replaces the part, seals the scalpel, and puts it in line with the scalpels he's already completed. Every so often he leans back to watch the recovering mechs on the berths in the 'Bay. Ratchet's optics narrow. "That's not our tech," he says.
