Hurley was on the list that Michael had of those he was to bring back .

also , about my theory about the others wanting another newborn , there is Sun , being already pregnant ..... but then only Jack , Jin and Kate know so far , right ? ...... And there she is , out there , close by with Jin and Saied . I don't know , seemed possible . the Kate ,Jack and Sawyer triangle ..... What other reason for just wanting the three of them ?
