anyone agree with me that regina wasn't really "evil evil" によって the end of the stable boy episode where she finds out that snow is responsible for ruining her happiness?

I agree that Regina wasn't evil によって the end of that episode. Like あなた said, she merely spoke out of resentment and anger towards Snow. If anything, Regina should have *seen* this coming. Obviously children will do anything for the greater good for that one particular person, in this case, Regina. Snow merely confessed to Cora about the relationship between Regina and Daniel because she assumed that her mother would have intervened into Regina's life in a positive way. Obviously this backfired.
Had Cora been もっと見る understanding and altruistic for her daughter's ハート, 心 (no pun intended), she wouldn't have killed Daniel, but rather let him live alongside Regina and little Snow. But then, things wouldn't be where they are right now. :/ Meh, I digress. 48+ hrs. 'til season 2 ep 1 begins, and I'm already seeing ムーラン and Aurora. *-*

I still don't think she's evil evil.

We haven't actually found out 'how' Regina became 'evil' yet....I think we'll find out in the episode 'We Are Both.' On how she met Rumple and wanted to get away from her mother forever. He obviously made some 'deals' with her....So I'm curious to find out!
