So if I read the premise of the first post correctly, it went something like this:
"MrEko's death was another plan by TheMan to keep a Brothah down?"
damn crackahs.

It has been reported that AAA's contract was not a long-term contract, just the same as the other actors. AAA was unsatisfied with receiving the script the DAY of shooting, giving him little time to prepare--and he was frustrated. (I don't blame him. Personally, I don't know how Jack/Kate/Sawyer/Locke/Hurley did the S2 finale with less than 1 days script reading--let alone shooting dual epis at the same time.)
AAA had input into how he would leave the show and coincidentally--it was AAA who came up with the name "MR Eko" as opposed to "Eko" which was what was originally written into the show. AAA felt that, given the impending storyline, that MrEko put him on the same path in recognition or in search of faith as "MrLocke"--which I thought was a brilliant idea.
Nonetheless, Damn TheMan for keepin a Brothah down!
cheers
