"Well," says Isabella, peering at the disappointing results from the computer analysis of network activity on the planet below. "That's going to be... inconvenient."
"Nothing concrete. I've thought about it, but don't have a general approach for the situation. Could skip this one. Could disguise myself - they're humanoids, if I land in a desert I can wear one of those headwraps and be unidentifiable - and directly offer the plans to someone and disappear. Could hide them somewhere where they'll be found, with a dead scientist's name on them."
"I don't think my computer is sharp enough to narrow it down from here. It might be necessary to collect a body of each one's work, learn to read it, and come back later when we've picked one," muses Isabella. "Or I suppose we could choose at random."
Eventually they find a place where he was known to visit. "But," Isabella says, "if it's been not found for the last month - one of us should go down in person and tuck it into a nook someplace. Landing it on a desk won't work. Unless you can do the math precise enough to find a place to tuck it all rolled up where it'll still poke out enough to be spotted soon."
"I think I can pass for a local more easily, if only because I'm female and have an excuse to wear one of those headwraps to disguise the fact that my ears don't touch my shoulders. Of course, if I get caught at all, I hope you will be paying attention to a moment when no one's looking to fetch me up again."
When she did this herself, she had the transporter on a timer. This time she can just say into the communicator she picked up when shopping on Betazed, "Going up."
They're on the edges of Federation space - Isabella cannot venture too far afield, or her Prometheused planets will run into Klingons or Romulans or similar before they run into Starfleet, but she does have to go a ways to get anywhere that meets her criteria. The trip will take four days. Surely they can find ways to occupy themselves.
He could carry on teaching her Klingon, for example.
Isabella docks at one of the stations orbiting Earth, and refuels so she doesn't have to do it after having decided it's time to leave the Solar system. And then they can both head to the shuttlebay and board a craft that will take them right to Phoenix. All very convenient.
Renée is there to meet them at the port. She hugs Isabella. "Welcome home, my Bella, how have you been, is this your young man?"
"This is Lalita," says Isabella, leaving aside the question of his youth. "Lalita, this is my mother Renée."
"Oh. Oh my," says Renée. "All right. So you went to Betazed."
"And his ship was retrieved but would not admit of repair, and so it now belongs to a museum and Lalita keeps me company on my surveys."
"Lalita has been teaching me Klingon," offers Isabella.
"Oh, say something in Klingon!"
"This is a sentence in Klingon," recites Isabella obligingly.
"There was one very lovely nebula. We took pictures," says Isabella.
Then they check out a black hole, and then they are off to their next recipient of largesse.
"Oh, this is easy," laughs Bella when the computer summarizes the state of scientific exchange on the planet.
Putting the plans online rather than on paper means doing a lot of cutting-and-pasting, since their systems can't actually type these letters, but eventually the thing is done, the name is registered via elaborate proxy that pretends to terminate at a broken server, and the equations are posted.
(They get to watch reactions in real time: "Whoa, this is revolutionary!" "It'll never work in practice." "Where would you get enough material with the necessary properties?" "This is the most elegant equation set I've ever seen.")
And off they go! They "were never here".
