Drift lets out a shuddering sigh of air from his vents, a small trickle of relief dripping into his optics when Ratchet understands him. Bedrest has never sat well with Drift, but he knows Ratchet is working with limited resources, and he knows -- he trusts that Ratchet is doing everything he can. Drift's optics flicker slightly, looking Ratchet over for the first time, and he sees the crutches, the way Ratchet is leaning heavily on one side. He can't see below the waist, but dull alarm flickers over his face, his slackened mouth pulling into a frown.

What happened?
