It does seem that way, although it's hard to tell whether she meant it as a Dreamer's intuition or just a logical deduction. Still, I'll concede that part of the point. The thing with Gawyn made it shaky enough already.

I don't think there's an answer to the criticisms that she was not in fact sure about the globe dream's meaning, and that (most importantly) her concern about the seals was not prophetic, though.
