Well, it seems like Dewey Wins didn’t air.

The episodes in CN SEA’s schedule included Dewey Wins and That Will Be All. Even though the episode synopsis was kept the same, Dewey Wins was replaced with Off-Colors at the very last second. It at least confirms that the episode exists, but I guess we aren’t getting it yet.

Yep, a new episode is airing in Southeast Asia.

From Misseps:

Steven Universe S05E05 - Dewey Wins
HK Airdate: August 25th, 2017 at 5PM GMT+8
Synopsis: Steven helps Mayor Dewey run a difficult campaign.
NOTE: Listed as S05E05, but could be based off production codes.
NOTE 2: I have a stream (720x576p 1.2Mb/s + 64Kbps mp3) to cap it.
I’ll try if I can find a better one.

What do you think the episodes will be about? I feel like it’s gonna be about Lapis, considering she wants absolutely nothing to do with the possibility of another conflict between Earth and Homeworld.
