Yeah I agree with that entirely! Yet I still think it does make a difference. I didn't say it was a "Yen is nice" versus "Yen is a bitch" point. But on one hand she doesn't care whether Geralt cares about her or not as long as he kills that dragon, on the other hand the fact that he will do it for her because he cares about her is important to her. I agree that in both cases it was a shitty move to make and that in both cases it wasn't out of maliciousness. That was not my point.
Anyway, letting this go now, sorry guys :unsure:
She knows he cares about her, which is the whole reason why she asks him to kill the dragon for her. She was pulling a "come on, Geralt, we'll make love on the furs afterwards" move because she knew it was what he wanted. I don't know how much Yennefer wanted it at that point, but she used it as a barganing chip anyway. She does want it later on, after the baby dragon, when they share a moment of honest tenderness.
