Near the end of tonights episode, Kate and Jack find a food rations parachute in the jungle.
This explains how the hatch was restcked and always filled with food, the 2 man team were locked in the computer foom whilst the hatch was restocked. I feel smart because thats what I said at the begining of this season
.
Also if you have an eye for detail (Comes with being obsessed wit LOST). You will have noticed that both the Macaroni and Cheese from this weeks episode, and the DHARMA cereal from lastweek had the same barcode. "DI 9FFTR731".
Also, what else do you think they will find in the chute-box? Obviously from the promo it will stir up some contreversy.
