I agree about the bean being one time use, too. By ‘going to at least one other world’ I know, TheGoldenKey and I have discussed her theory many times, and we both believe that Bae went to Neverland. That doesn’t mean he used the bean more than once. Everyone keeps saying, the BF sent Bae to a world without magic…well, we all know the BF lies. If Bae went to Neverland with the bean, he would be able to travel to our world, as Peter Pan could travel freely between our world and Neverland- he wouldn’t need the bean, or another bean…
About the ‘misleads’…yes, taken alone, they could’ve been misleads, as in The Doctor w/the Oz nods. However, those weren’t just nods & misleads. They were pointing out the fact that we will indeed be seeing Wizard of Oz. K&H have confirmed this in an interview in Entertainment Weekly.
I am sooo looking forward to seeing Oz! 🙂
