Walt on the Milk Carton
Walt's picture appears on a milk carton during season 4.
In episode 2 of season 4, during Hugo’s dream sequence, we see Hugo in the hatch’s pantry eating an assortment of food and candy before picking up a carton of milk. While drinking the milk Jin comes in and they have a quick chat where they are soon joined by a man wearing a chicken costume. Wait, what?
What many fans missed however, is that on the back of the milk carton Hugo was drinking from is a picture of Walt, Michael’s missing son who was kidnapped during the finale of season 1.
The Milk Carton’s text simply states Walt’s date of birth, gender, height, weight, hair color and eye color. Below that it also reads, “Last seen: Middle of nowhere”.
