I thought this was a really good episode. I do feel sorry for Regina, she really does seem to be trying to clean up her act, but as soon as something bad happens everyone assumes it was her. Granted her mother did frame her, but even before they saw her transformed mother, they didn't pretty much just assumed she did it.
I'm happy that it looks like Hook at least will be discovered in next weeks episode. I hate it when they drag storylines like this out forever.
