I did like how Smee came up and it took me some time to recognize the famous red cap/striped shirt.
Yeah, I was trying to figure out who he was going to be!
I loved that Hook called Rumplestiltskin a crocodile when he first saw him as the Dark One, and I hope we get to see Neverland at some point.
I liked the little reference to Game of Thrones as well
This show has got so much going I sometimes forget that it's only in its second season. There's been so much backstory and character revelations it seems like it's been going on for much longer than 30ish episodes.
