You know that Jin actually had die in Season 4 but why Lindelof and Abrams bring him back in Season 5 ? Also Claire in first half season 1 was credit in episodes where she appearance why writer give her main characters status only in second half . Like Ilana in Season 6 she had have some biggest rule but later writer kill her why . Why writer change these things ?
I also forget say that writer had plans for Danielle that she have flashback episode but later they change plans why ?
