Book Three: The Bodysnatchers
Once again starting off strong, the Doctor gets into a scuffle with a sick man named Tom, who shoves him hard enough to fall over, resulting in him cracking his head against a wall and briefly disorienting him
The Doctor is grabbed and roughly manhandled by two security guards at a factory, who attempt to hurt him via squeezing too hard and wrenching his arm behind his back, but he seems unbothered and not particularly hurt.
Caught by a group of Zygons in a Zygon ship, the Doctor is strapped into a machine intended to take his physical and mental “print.” However, thanks to his telepathic abilities, the Doctor resists the machine until it becomes too painful from the increasing mental pressure before finally falling unconscious, breaking it in the process and remaining asleep for sixteen hours.
Whilst diving to infiltrate the Zygon ship, the Doctor is dislodged and tossed to the bottom of the river as it begins to move, hitting it hard enough to stun him for a moment.
As he clings to the ship, he’s occasionally jostled hard enough to bash his face into the outer hull/shell of the ship
Entering the ship through a ‘breathing hole’, the pressure and force of the current is enough to club him into unconsciousness, and is described as feeling like “his body was being pounded with chunks of concrete”, and he is left passed out without the breathing tube to his oxygen tank, though he by some miracle doesn’t seem to inhale any water
Balaak, enraged by the accidental deaths of every Zygon on the base, attacks the Doctor with his stingers, stabbing him in both sides of the neck and poisoning him. Because the warlord is dying, however, there is not enough poison to be lethal, and the Doctor can heal himself.
Caught in an underwater explosion whilst attempting to escape the self-destructing ship, the Doctor loses his bearings and can’t find the surface, and once again falls unconscious due to a lack of air for an unknown amount of time/several minutes before he’s pulled out and expels the water again.
