I suggest you get used to waiting. I downloaded the lastest raw to check if the flashback was over yet, and Episode 20 is still flashback.

But think about it this way, you're geting TWO, count them TWO series for the price one!

EDIT:

See now I'm confused! Cause episode 20 was a flashblack, but the preview for 16 looked like it was back to the present. WHAT DO I BELIEVE?!
