There was an exclamation of "No! Not the Mind Probe!" before the Castellan was escorted from the room. The Doctor tried to convince his old teacher Borusa to let him go and question the Castellan, but before he could reach the door to follow the group that had just departed a Staser shot rang out. Opening the door, The Doctor could see one of the Chancellory Guard kicking a Staser away from the hand of the prone form of the Castellan.
"You should probably stay back. We don't need a Metacrisis on our hands on top of everything else." one of the guards said, moving back himself to stand near the Commander who had moved to a discreet distance from the Castellan. "As soon as he's done regenerating, it's off to the cells with him until his brain finishes unscrambling, and then it's the Mind Probe for him."
"What do you mean done regenerating? He's dead!" The Doctor exclaimed after he'd gone forward to examine the body rather than hung back where it was safe like he should've. Considering the fact that the Castellan hadn't been dipped in radiation or something like that, he had been reasonably certain that it was safe enough to get close enough for an examination since it wasn't like the hallway was going to blow up or anything.
"No he isn't, he's just being slow to regenerate." the Commander said, poking the corpse with his boot "The Castellan's got...he's got...Er, how many more lives does he have left?"
"Uh oh." one of the other guards said.
The Commander of the guard knelt down to examine the body.
"Well, I'll be damned. He's dead!" he exclaimed.
Three hours later after the mess on Gallifrey had been sorted out:
The Castellan groaned as he awoke. From the feeling of it, he'd regenerated again. His regenerations had always been rather...quiet. In fact, the first time he'd regenerated after he'd died in his sleep, he hadn't known anything had happened until his wife had woken him up by screaming, calling him a pervert, and attacking him with the bedside lamp. As the headache started to abate somewhat, he took stock of his surroundings.
"What the fuck am I doing in the morgue?"
