anyone notice similarities between the season 2 premiere and finale?

i might just be pointing out the obvious but i couldnt help but notice how similar the season 2 premiere and the finale are. in both of them, there's something that's threatning to destroy the entire town and also regina is the victim and the charmings go to save her thanks to some persuation from henry. also in both episodes, emma and regina join forces to get rid of the thing thats threatening the town. also in both of them, main characters go missing. in the season premiere it was emma and snow when they got sucked in the hat to fairytale land and in the finale, it was henry. also one more is that they both show mulan, aurora and phillip. :) and also in both of them, we only briefly see neal. its just amazing how many similarties there are between them :) lol
