Oh, that throws an interesting spanner in... I had assumed that he's knocked up, as in a typical abduction, but now I'm not so sure any more. That could still be the case, but.

"He has to be convinced."

"They will talk to him, and make him understand."

And Stella isn't aligned with the rogue PTs, who knock up sims without regard to the official guidelines. So now I'm thinking this was a conversion attempt. The alien belief system could be interpreted as cultish, from some points of view, which makes this look like a brainwash attempt.

Not that I pretend to know where you are going with this. I am just thinking out loud, or in type, rather. ^_^
