The Doctor, for the first time since Prince met him, turned in irritation and rudely told him: "Shut up, Prince."
He was obviously incredibly annoyed about something, but before Prince could ask what it was, he pointed his screwdriver at the Angels and destroyed them.
"Listen up, Black Guardian!!"
Discord appeared before him, chuckling.
"It's been a while since you called me that, Doctor."
The Time Lord didn't lose any time.
He grabbed the spirit by the beard and looked into his eyes.
"Listen up, you misassembled circus freak, I don't have time for games. I've lost enough time as it is and I know you're not nearly as powerful as your previous embodiments. You are everything I despise, everything I stand against and I won't think twice about ending your life. So, either give me the key of Rassilon, or prepare to become a pigion toilet once again."
The spirit said nothing for a few seconds, even after yet he stallion left his beard go, still dazed by his words. He then groaned and snapped his fingers, revealing a floppy disk-like artifact on a necklace around Prince's neck.
"You've really become a bore, Doctor."
The Doctor pushed Prince outside, not even turning back as he exited himself.
"Desperate times call for desperate measures."
