Finally caught up on all the episodes. Loved the finale. Random thoughts:
* Emma reviving Henry with true loves kiss was great, because it shows that true love doesn't have to be romantic.
* It looks like those with magic will get their magic back now. If Regina does, I have a horrible feeling she will at some point try to recast the Dark Curse. Which of course requires the heart of the one she loves the most. And what did she say to little Henry at the hospital when he woke up? And what was the name of the last person whose heart fuelled the Dark Curse? Yeah, wouldn't want to be in Henry's shoes come Season 2.
* If magic is back then Jefferson's hat will work again, which gives people a way back to their own world. Also, can I just say how amazing that damn hat is? Even with minimal magic powering it he was able to use it to reach through not just worlds, but time
as well - he snatched that apple from the past. He could potentially use the hat to alter the past. If it had full magic, it might even be able to send a person through time.
* If magic is back, August should recover.
You'll meet the writer of the book a few episodes down the line.
I don't think we did. August didn't write the book, he just added his own story to it while he had his hands on it. From what he said, he completely skived off his mission and just had fun until the day that Emma arrives in Storybrooke. Then he starts turning back into wood, and it's only then he cares again about doing his job.
Someone else wrote that book. It might never come up, especially since the curse has been broken and I don't think the book will matter anymore. But still, I would have liked to know who wrote it and how Mary got her hands on it. It means that there was someone else who knew about the curse, and somehow knew everyones stories.
