"Once Upon a Time’s series finale will air over two weeks, starting Friday, May 11, and concluding Friday, May 18, at 8 p.m. ET on ABC."

I'm really confused about this. 7x22 has been confirmed to be the *official* series finale, but every website says both 7x21 & 7x22 are considered series finale. Does this mean 7x21&22 are just like 6x21 & 6x22 (The Final Battle) and act as a single (two-part) episode?
