I don't think Hurley worked at the mental hospital. I think he was in it.

He mentioned something to his mother toward the beginning of the episode about what all he'd put his family through lately. I think that means what with the going crazy and all.

And the sextuplets are in B'ham. Centerpoint, methinks. I had to restrain myself from going down there and jumping on stalking Ty Pennington.
