Edea's eye. Can someone guess what does her pupil resemble to?

It looks like 'inverted' Squall to me, which makes sense considering the situation at the time as this photo took place right after when an icicle's struck against Squall.

And during Squall's dream, after the final battle, this shot repeats itself when Rinoa is seen leaving Squall at the dance hall.

So, what does all this mean? I think that the eye represents a sign of Squall when he's really down. I'm not sure what's the right word to use...
