... Will is the White King at the moment where Alice tells her story to her daughter. But we don't when this scene happened in OUAT timeline. We clearly know the time is slower in Wonderland than Storybrooke (Will go back to Wonderland in 2.01 and W.11 happened before 2.03).

Soooo, we don't have any proof that the S4 is before this scene at the end of OUATIW. Unless it is explained, S4 could be after OUATIW and so Will does not have to come back to Wonderland (especially if Ana is killed, which it won't happen I hope)
