They gathered in a clandestine meeting in a top-secret location.

"We're all sworn to secrecy with repercussions; it's safe to talk about 'it' here. First on the agenda are profiles," said the moderator.

A hand raised.

"Yes, Jacob?"

"It's a question about what's potentially as dangerous and revolutionary as the technology itself. Who do we send, and does one size fit all, or are there differences?"

"What differences?" asked Rebecca.

"Forward or backward in time …" answered Jacob.

"Please explain what you mean …" Rebecca raised an eyebrow while jotting down notes.

"Well, being a therapist, I've encountered fundamentally two types of people that would either be beneficial or disastrous. There's the isolated, lone individual who doesn't care much about anything. Then there's the other extreme, the passionate family person, who cares about them dearly and is fearful of consequences."

"So, who goes where?" asked Rebecca.

"Well, clearly, the isolated one goes to the future … no matter how bleak, they'll be fine with whatever happens, and the family person is obvious."

"Maybe not obvious to everyone," responded the moderator.

"Right … The devoted person must go to the past. They wouldn't want to harm loved ones. They have the most to lose if anything goes wrong with the timeline."

"And if they decide to change anything?" asked Sarah.

"We won't even know the difference, which might be for the better. But sending a loner into the past would most certainly turn into a disaster."
