Will I just forget here, or something more?

[ Was it like the boundary outside of Storybrooke? Would she forget herself all over again?

But wait. They could stop that - they had before. Rumple had kept his memories over the boundary line ]

What about the potion that Rumple used when he went to go find Baelfire? That let him keep his memories. If I take that before going back to Storybrooke then things could be different.
