This has spoilers for the episode Good Form, which aired on 10/27/13 in the US.
It also has a spoiler for the title of next week's episode...
This is a bit disjointed as I just finished the episode, and... Feels!!
1 - Hook's back story... Damn, they know how to give emotional punches! Hook was a honest, decent man. Who's king brought his family to ruin. Can I hug him? Please?
2 - Peter Pan at the end of episode... I think he miscalculated. Yes, Hook wants a relationship with Emma. But, he sees Baelfire/Neal as a son. I think Peter won't like what happens... If the writers decide *not* to go for the obvious "I'm going to keep this secret to have a great lovelife (Bow Chicka Wow Wow) until he pops up and, um... oops!"
3 - Who the hell is in the other cage???
Oh wait! The next episode is titled Ariel... Is she in the cage?
I saw the title of the episode, and thought "Finally!!"
