This seems pretty far fetched even for Lost writers. 🙂 I think that there must be some truth to what Cora said…some…not all. I don’t see them combining characters that way. I don’t see anything to suggest that Phillip is in Hook. There would probably be a battle between the two souls inside his body and we would see a change in personality if the souls were battling it out. Hook has been a very consistent character in this show.
These writers are known for their nods to things they like…Stephen King, Lost, etc but building off another show would be too close to plagiarism and not something I would see them doing at all. I like Hook being Hook and leaving his other character portrayals where they belong…in other shows. 🙂
