I have never been in a fandom before where some shippers tell others they are not allowed to like their ship or support it anymore because it didn't happen in the movie. WTF is up with that? Who is to say what is viable or not? Have you ever been in other fandoms??? I need to leave this fandom for real. Pretty sick one where ships are involved.
You wouldn't believe how many non-canon ships I've shipped. It can be done! And for the record, didn't the T's say Sparrabeth is just as much a canon relationship as Willabeth? Just as important to character development. But I digress, I could post it all here word for word, no one would believe me.
Anyway I voted for...Jack, always Jack no matter canon says. That's what fan fiction is for. To me, and what *I* see, they match better. Better chemistry, better vibe.
That is my personal opinion. I don't like Willabeth, and I never will support it.
