I read some online comments that Adam Horowitz had tweeted that the "sneak peek" is actually a leaked clip from the unfinshed episode; which stands to reason since it really spoils way too much stuff. Now I kinda regret watching it.

Regina's change of heart does seems rather sudden - from "we must destroy my sister" to "heroes don't kill" in just one episode. But it does show that she has finally come full circle and has reverted back to who she was before losing Daniel. First she found a new soulmate and made up with Snow, even protecting her from harm. And then she proved her true love for Henry and as the final step she gave up on her vengeance and was able to use light magic to defeat Zelena as a result.

I doubt Regina will turn evil again, she has really progressed too far for that now.
