 Durand was never informed of his character 's arc and only learned more of Keamy 's importance to the plot as he received new scripts ; thus , he was thrilled when the role was expanded for his third appearance , in " The <unk> of Things to Come " , when he kills Alex and Durand compared his excitement to that of " a kid in a candy store . " He also stated that " you really don 't know what 's going to happen in the next episode and you get the scripts pretty late , so it is pretty secretive and it 's kind of exciting that way [ because ] you 're really forced to get in the moment and say the words and play the guy " . Durand was initially met with negative reaction from fans on the street for this action and he defended his murderous character by arguing that it was actually more Ben 's fault for failing to negotiate with Keamy ; later , fans warmed up to Keamy . Despite the antagonist 's increasing popularity and fanbase , it became apparent to Durand that fans were hoping for Keamy 's death in what promised to be a showdown in the season finale . Throughout his nine @-@ episode run , Keamy never receives an episode in which his backstory is developed through flashbacks and Durand holds this partially responsible for the negative reaction to his character , saying that the audience " [ has not ] really seen anything outside of Keamy 's mission , so I think they definitely want him put down . " Following the season 's conclusion , Durand stated that he would not be surprised if his character returned in the fifth season and concluding that " Lost was really fun . If I can have that experience in any genre , I 'd take it . "
