Hurley chases after his old imaginary friend in the jungle, and his relationship with Libby develops. "Henry Gale" tells Locke that he did not enter the numbers, and Locke questions his commitment to the hatch. Hurley remembers his time at a mental institution, and surprisingly, so does Libby. Dave was full of information and honestly had me really confused and normally I don't really get confused by this show the whole its in your mind thing was crazy but I knew it was bull crap because this episode would have happened near the end of the series.
Overal a Brilliant and informative episode with plenty going on.
