Doctor and Ben Tennyson in “Unfinished Business”

Your grandfather has suffered a severe concussion. He'll be out for several more hours. He also has several lacerations and a broken leg.

He's gonna be okay, right?

For a man his age, he's remarkably strong. He'll be fine after some rest. Now it says on his admittance form he was hit by a car bumper. Did someone back into him?

Actually, the bumper flew through the air after this robot drone blew up the car.
