A few days later...
The Doctor had the new batch of Nanoprobes, but was unwilling to test them on anyone. They were too dangerous for use, especially since they would turn people to Borg, and begin converting flesh to mechanical systems. Each of the Nanoprobes had a complete plan for creating Borgs stored within it. They had managed to elimate the creating perametres, but not the frequency modulatiion for the communications.
Having that inside a persons head would be like having thousands of people in your head. Occumency wouldn't stop it, and you would have to have a strong mind to survive.
She left the vial alone, and somehow, no one knows how, Mr. Black drank it with his morning coffee. After complaining about a slight headache, which disappeared, he was normal and unaffected by any Borg urges.

Picard stared at the Borg cube in wonder, especially as the commander of the vessel had contacted him, without saying that 'Resistance is futile. "Excuse me, could you repeat that?"
The Borg who'se attention was caught by something else turned his attention back to Picard. "Hmm? Oh, sorry about that. I said we're are the Borg, and we're just people on vacation. Could you recomend a place where they have interesting sights, food and conversation?"
An uneasy feeling fell over the Captain as he watched the beings that he'd spent so much time fighting. He had to concede that negotiation was the Federation way, he had to admit that the borg had changed since the intercession of the mysterious Mr. Black. But he would be damned if he was going to play tour guide.
That was what the diplomatic corp was for.
