I think I know. The actor that plays Sara left the show, she has a child now, and she wanted to be killed off. Soooo..
I am guessing it's her head in the box.

This creates some new problems-- Does Link tell his brother she's dead, or lie, so he doesn't do something crazy..
Kinda sucks. I KNEW the second I saw how they were leaving her out, and not seeing her in the opening credits was telling.
