im talking about the sceen whre the doc takes sayed and dsmond back and sees a pile of blood

Micheal, the spy for Ben is spying as a Janitor, he was th one that put the note in, he also was supposed to clean up the pile of blood but left it to clue Sayeed and Desmond on how bad the Captain was , he was on the corner so they wouldnt recognize him, but they did, However, Sayeed and Desmond wer smart enough not to blow his cover .

now heres something else i think
why would he do this?

Simple Ben ses that Micheal would do anything to get his son back, so he simply goes out and gets the son again, he asks and he blackmails micheal to do it
would you guys agree?
