I guess I'd be curious enough to have to discuss it, maybe weeks/months down the road and see if I could get a better idea of what happened; if she had an eye problem, if it was just an odd reflection of the light from where you were sitting or if she had lost a loved one or knew of someone like your nephew or what. For all you know, she might have been working with your nephew :-)

Sometimes I think the rules of crisis apply when we are talking to our T and we can be all "official" and give the facts/details as removed from us, as if we were talking about a news article we'd read that morning, but then, when confronted with the time/place it's okay to be upset, then we are freer to do that. That's kind of what wakes and funerals are for?
