The stranger who called himself the Doctor, and refused to answer to anything else, found himself escorted by Janeway and Seven to the briefing room. Even though he was a new lifeform, Janeway decided to loosen security, since it seemed that for once this alien was exactly what he seemed - friendly.
As they entered the briefing room, Janeway asked, "What did you call that blue box, Doctor?"
Smiling roguishly, he made a motion for Janeway to enter before him. "Actually, I hadn't. But it's the TARDIS. That's what my old ship is."
"Ship?" Tuvok stood by the table, tricorder in one hand. Looking at their odd visitor, Tuvok set his tricorder in its holster. "Your . . . TARDIS is impenetrable to even the most intense sensor scans. But the dirt on it, according to readings comes from 20th century earth."
The Doctor allowed himself a seat. "That is where I currently am from, my good sir. England to be precise. But I am not from your reality. I have been sent here by my people, who should learn to do things for themselves, but that's another story, to assist you."
Janeway felt a fascination for this man. "Assist us in what?"
The Doctor's face lost its jovial look. "In preventing the conquest of your galaxy, Captain Janeway. I am pursuing my own personal enemies, the enemies of all intelligent being that wish to be free."
"Who are you pursuing?" interrupted Chakotay, entering the briefing room.
"Doctor, this is my First Officer, Commander Chakotay."
The Doctor rose and offered a hand. "The Daleks, my boy! The Daleks. They've made contact with some race here that calls itself the Borg."
A deafening silence reigned through the briefing room.
Seeing that the word had some meaning for these beings, the Doctor began quite animatedly to explain who he was; a Timelord. He told the truth because he saw no reason to lie. Why he was here (at the intervention of the Celestial Intervention Agency) to stop an alliance between the Daleks and the Borg, an alliance that could doom all realities. The only thing he left out was how he had traveled there. It just didn't occur to him to explain it to his new friends.
In reply, the crew of the Voyager gave the Doctor a shortened version of the six years they had been here. How the Caretakers complex had been destroyed and the ship stranded for close to five years. Of the Borg and their near fatal incursion into Fluidic space, how the Voyager had saved the Federation's deadliest enemies, which almost resulted in them being assimilated, but instead gave them Seven of Nine.
The Doctor seemed particularly fascinated by the concept of Fluidic space. "I've been to many places, but space that is basically a huge ocean? That is something I'd like to see. But that's for another time. The question now is, how do we stop this alliance from taking place."
Seven, wearing a look of disdain, said, "I do not see this as possible. The Borg do not ally, they assimilate. They use whatever they can from the races they absorb. There is no sharing, no concept of self."
"Honestly," replied the Doctor. "I can't see the Daleks seeking allies either. They use races as slaves and they have a race of beings they use for their dirty work, the Ogrons, but those worthies are barely capable of thought, let alone any complex actions."
"But," said Janeway. "You were sent here for a reason."
Before the Doctor could reply, Harry Kim's voice erupted over the loudspeaker. "Bridge to Captain Janeway."
"Captain, you'd better come to the bridge. Sensors have picked up a Borg energy signature."
With a hurried, "Follow me, Doctor," from Janeway, the briefing room emptied quickly.
