*Borusa continues...
"As you know, validium was created as the ultimate defense for Gallifrey.  Rassilon decreed that only the President could authorize its use, and no one has mentioned the name validium for centuries.  The greatest weapon known to our civilization, and now it has escaped."
**
"Escaped?  That's impossible!"
**
"It had help."
**
"Who would be so insane as to unleash validium into the universe?!  It should have been destroyed millenium ago."
**
"You did, and it wasn't."
**
"What did you say?"
**
"I said, it wasn't destroyed, and you released it."
**
The Doctor sat back, stunned.  His mouth opened and shut a few times, but no sound came out.
"When?  How?  Why?  Are you sure it was me?"
**
"That is part of the reason I am here: to determine if I should kill you now- or later- for your crimes.  Personally, I think later will be fine.  We need your help to put the genie back in the bottle."
**
"So... I did release validium... oh my...  this makes all these petty wars and territory squabbles pale into nothingness by comparison."
**
Borusa sneers in contempt and waved his arm to indicate everything around him.  "All of this is history to me: it means nothing.  They will fight until the end of time.  The question is: when will that end come?  If you don't help, it may be very soon indeed."

*Borusa and the Doctor sit at the table as requested- the Doctor putting his legs on top and leaning back in his chair, while Borusa sits gingerly on the edge of his seat.  At the mention of his name, Borusa turns his scowling face to Mannion.*

"I may have volunteered to be the one to warn this galaxy of the danger of valdium, but I do not have to be subjected to the indignities of your so-called security people."  

He turns to the Doctor and says, "You know what to do.  I have said enough."

*Borusa touches his wrist and fades away before Mannion's astonished eyes.  The Doctor seems to expect this, and merely grimaces at the enormity of the task ahead.*

*Borusa leans in and tells Doctor why he is on Avalon.

"As you very well know, Doctor, Gallifrey is at war.  You may also know we are losing."
**
"That musn't concern me- I am not involved."
**
"True.  But we need your help to prevent the war from becoming more than it already is.  We do not have the resources to do the job, but you do."
**
"Whetever it is, I won't help.  It is your war."  The Doctor gets up to leave, but Borusa says a quiet word that makes him sit down again quickly:
**
"Validium..."

*Borusa glares at Mr. Mannion and raises and eyebrow.

"I think you'll find that valium is a 20th century drug, young man.  The substance we are discussing is validium- much more destructive than you can possibly comprehend.  Now, just go away, and take your petty schemes and plots for power with you."

*Borusa actually smiles at Mannion's words.*

"Doctor, doesn't he remind you of Koschei?  Such spirit.  Perhaps he is just who you need to help you- he seems to have more discipline in his words than you do in your whole body."

The Doctor rolls his eyes at this last comment.  Borusa was entitled to his opinions, and nothing he could say would change those opinions anyway.  Besides, Borusa was right, it was a good idea to have someone like Mannion along.  No doubt this situation would turn ugly, and the Doctor hated carrying weapons...

*Borusa sidles over to a comms booth and ducks inside.

Borusa: "Computer?"
Computer: "Hello!  May I help you?"
Borusa: "Yes.  Send a private message to the Doctor for me."
Computer: "Please specify which doctor to whom you would like to send a message.  Do you need medical assistance?"
Borusa: "No I don't need a doctor, you antiquated adding machine.  I need the Doctor.  He's aboard this station, I've traced him here.  He's part of your crew, I believe, working for the Terrans."
Computer: "Please wait while I search for the Doctor."
************************
Computer: "There is a medical doctor whose name is Doctor, is this the person to whom you want to send a message?
Borusa: "Yes, yes, that's him.  Are you ready to record my message?"
Computer: "Whenever you are ready, sir."
Borusa: "Right.  Doctor, when you get this message, meet me in the... Computer, inset the name of this area to my message.  Sign off the message with the words 'an old friend from home.'"
Computer: "Shall I send your message, sir?"
Borusa: "Yes, and do it quickly."
