OUAT S3E20: Kansas
So I'm pretty much sure that most of us Oncers have seen this clip after it has been leaked out even before the episode is officially aired.
Regina is able to use light magic signifying a change in her destiny.
And why do I have an impression that the circle thingy looks like some pokemon battleground arena that shaped like a pokeball?

Hah. I can't unsee it!

Do share with all the ONCERS out there!
