I was WATCHINg the episode AGAIN with my Night vision Googles and a panama hat on TO spot MORE clues and IT proved a MAMMoth success!!
It appears THAT Hurleys Life-jacket was ACTUALLY the smoke MONSTER in disguises!! When HURLEY reaches in TO GRAB baby erin you CAN see his JACKET on then 1 frame LATER it is GONE!! This proves more OF my theories ABOUT lost and ONCE again propels as the leading Lostigator in the Field!!
There is NO need to thank me FOR this
