At the end of "The Bounds of Reason", the first story in the collection Sword of Destiny, the second of the first two Witcher short story collections, we see the following exchange between Yennefer and the dragon Villentretenmerth:
"Forgive me my frankness and forthrightness, Yennefer. It is written all over your faces, I don't even have to try to read your thoughts. You were made for each other, you and the Witcher. But nothing will come of it. Nothing. I'm sorry."
"I know," Yennefer blanched slightly. "I know, Villentretenmerth. But I would also like to believe there are not limits of possibility. Or at least I would like to believe that they are still very far away."
What exactly does he mean by "nothing will come of it"? Does it just mean that they will have no children together (due to Yennefer's barrenness), or that their relationship will not last (as it didn't last last time - indeed, they've only just got back together again)?
Is the meaning of this phrase more clear in the original Polish text?
