But it still comes down to how did August knew it controled the dark one, he wasn’t around with Rumple was locked up everyone else was under the curse.
Like I said, if Pinocchio was on NL at the same time as Bae and they met, Bae could have told him everything.
That can’t be right either remember Neil didn’t know August when then met the 1st time just before they put Emma in jail. No, there has to be something else or someone else that told Pinocchio/August about the dagger and how to use it. I don’t think August was in NL either, no one else can seem to jump around with out beans etc. I also don’t think the Mad Hatter knew about the dagger either only the BF, Bae, Cora, and the Duke knew about the dagger and how to use it before the curse came.
