Whether the Blue Fairy is sneaky or not…we definitely need more info. That “original power” thing keeps bugging me. Apparently it keeps her young…and doesn’t do much else so far except grant a wish every few decades or something. Let’s see some POWER! Apparently she’s limited by lack of wand / fairy dust but there has to be SOMETHING that an “original power” CAN do….right??
I also agree that Gold probably took the barrier down but didn’t have the strength to put it back up. I need to look but did he walk in first? Perhaps him walking through it breaks it automatically as the magic “recognizes” him and then he needed Emma to put it back up cause he just wasn’t strong enough. Just a thought.
