Sure we "saw" the demon seed break, but then that image of the seed looked more like a metaphor for the actual object than a view of the real thing, so the picture of it breaking might have been a metaphor for breaking it's hold on Natsu rather than breaking the seed itself.

And I REALLY don't want to actual physical object to look like it has leafes sprouting out on top... that would be so silly.

I know, it's more on the unlikely side, especially with how on the nose and unsubtle this arc has been so far, but it is still not entirely impossible.
