Not to mention, John Wesley Shipp's Flash earth is also apart of the same multiverse.

http://comicbook.com/2016/02/10/supergirl-cameos-in-the-flash-tonight-and-what-that-means-for-th/ In my opinion, I think that any character or concept that interacts with a Arrowverse character should be part of this wiki. John Wesley Shipp's Flash briefly appeared, but the Flash will actually meet and interact with Supergirl and Earth-Supergirl. I think we should stop thinking of it as a multiverse and just write about anything that is part of the stories of the Arrowverse characters.
