Kate not only loves eggs, as evidence by eating them in her mom's diner, but she also has ovarian cancer. She had to get them taken out to prevent her from dying. So she goes back to the island to get her eggs back!

I agree that it will have somthing to do with ovaries, but thats a but of a stretch

i think it has more to do with the fact that locke serves ben eggs, and the town they are in has eggs.

Maybe this episode will be crammed full of easter eggs. :)

Oh and lmao here at "and the town they are in has eggs."
