In order for me to respond to this, I have to first presuppose your fanfiction actually comes true, which I will not do. I will, however, note that a large portion of Hancock's character (and appeal) stems from her naivety, much like Margaret's did. The fact that she THINKS her love for Luffy is reciprocated is what makes the situation funny and enjoyable. We all know Luffy won't return those feelings, so why would Oda go the extra mile of having someone who already thinks she is married learn she isn't, learn what it is, ask for Luffy's hand, have the readers acknowledge it is a loveless and romanceless marriage, and leave Hancock to continue living in the same delusion she had prior to learning what marriage really is? This accomplishes nothing that had not already been established, while tossing out the window one of the more (or only) endearing characteristics Hancock has, her naivety. Again, for such an avid Hancock fan, you sure have an interesting view on her character.
Characters grow. She doesn't always have to be naive. And you're making the situation sound more complicated than it really is. Might I point out that Hancock asked if this was marriage not that it is marriage. It's conceivable too ask a source later to find out. Nothing convoluted. And Oda would go the extra mile because it's the perfect way to resolve her feelings. Simply sweeping it under the rug just won't do. The marriage would serve several purposes. It would give Hancock a certain feeling of security of staying at her island and waiting for Luffy rather than following him. It would give her a special role in the story, something she needs as her feelings make her far more special than another Vivi or Bon Kurei. Also it would elevate her love-sickness from plot device to character development.
For all I know. "For all I know" is for all anyone will know when this supposed fan-fiction takes place. Oda isn't going to leave us a note saying, "Don't worry readers, by the time Luffy becomes the Pirate King, the WG will be destroyed. 'Nuff said." Proving my point again about your understanding of Hancock, let's remind ourselves what type of person she is by quoting her: "You betrayed your people and set out to sea!! You left us behind!!" // "Be silent, you kingdom-abandoning traitor!" But of course everyone would forgive her if she left because she's beautiful, right? Or are you suggesting their crews would merge? Or would Oda just leave all of this to our imagination? These are rhetorical questions, by the way…
I just don't believe marriage automatically equals getting tied down and being forced to settle. Maybe Luffy will be happy to settle after becoming Pirate King? Maybe Hancock will join Luffy later World Government or no World Government. These are also rhetorical questions. The possibilities are endless and that's all they are, possibilities. Because remember, i never said she will marry Luffy, Is aid I believe she will marry Luffy because I think it's the best solution.
(Just reiterating the above…) Anything but naive misunderstandings wouldn't be "Hancock"; at least, as far as her 'relationship' with Luffy goes. Considering she already assumes she is married, why clear up her misunderstanding so she can formally ask Luffy, so he can leave having accepted to a loveless and romanceless marriage. What purpose does this serve, save wasting a chapter on near-filler material?
Luffy getting a life-long partner is filler material now? Regardless, I already explained this above on the naivety issue and the purposes the marriage serves.
"Just like Bon Kurei", you say? Bon Kurei went to prison. He was transported further down the Grand Line. Hancock, on the other hand, would be going back to her island. As in, the opposite direction of Fishman Island and the New World? Hey, I'm not saying it won't happen. She could, say, bring her pirate crew along to help Luffy in a battle of some sort later in the series. Is this something definite though? By all means, no. Luffy will be in the New World, she will be at Amazon Lily. Any other involvement, save reactions to Luffy's infamy, is at the moment completely unknown and unlikely.
Luffy going to Impel Down before the Ace thing was also unknown at unlikely. All I know is that Oda has a habit of bringing back old characters and taking them ways never imagined.
@brennen.exe:
It's her character TLC! How do you not see that? She's a woman who wrongfully assumes all men in the world are the spawn of Satan. She doesn't know what the outside world is really like, and is as blind in her love for Luffy as you are for her! That is what changed her character from 'hated bitch enemy' to 'likable endearing ally'. Take that away, of for a HORRIBLE purpose
less "resolution", and all we have is an understood one-sided marriage for a bitchy character who will be staying on her island for the foreseeable future.
Yes it is her character, but the traits she keeps displaying aren't just mindless gags. She's risking a lot for Luffy and she has feelings that just can't be ignored in the end. Feelings she keeps showing to a very large degree. It's something that has to be addressed otherwise it would be naruto and Hinata. And I have stated my reasons why the marriage is not without purpose.
