I read an article about Adewale whateverhislastnameis-secondpart and apparently he had never done a TV show before. He apparently prefers movies. Even last season, he said they didn't plan on having him stay very long. They knew from the beginning that he was going to be killed off, and apparently both Carlton Cuse and Eko's actor decided together that now would be the best time to do it, before things got really involved.
