Yes I honestly beliefe that Carla didn't predict this.

Why you might ask? Past history.

Except for the "orders" in the Edolas arc, I can't remember Carla making a single proper and true prediction of events that was more than 10 seconds in the future.

Sure she had plenty of vague premonitions and was able to actively search a large number of possible futures when destroying FACE, but that was her actively searching and again the potential futures were only seconds ahead of her own anyway, so the 10 sec thing holds true.

As for the water magic part, who would know Juvia's body and it's weaknesses better than she herself? She really wanted to kill herself. She thought so in her !!internal!! monologue, so there can be no deception in that.

But you didn't answer my question: Do you really believe that Gray would leave Juvia behind like that?
