White Rabbit - S1-E5
Continuity mistake: When Jack, Hurley and Charlie discuss water situation, the suitcase filled with water bottles repeatedly changes. One example: when Charlie carries the stuffed suitcase, then sets it down, it is open just a couple of inches, but when Jack walks away the suitcase is bursting with bottles, and is open at least 18-20 inches.
