Also, even if it on a different earth, Flash was on it, so that means it's part of the universe. But that's just me. It's part of the multiverse, yes, but not part of the same universe, and so far a crossover has only been one way. Earth Two is included in the wiki due to its prominence in the second season of The Flash, but so far Barry and the rest of the S.T.A.R. Labs team has yet to even mention Kara on their show. If crossovers become more frequent and characters from Supergirl appear on any of the other Arrowverse shows, the admins will be more likely to merge wikis, but for now the staff is choosing to keep them separate. This does not in any way mean that we are completely opposed to the idea, but more so that for now the criteria have not been met to consider a merger, as TimeShade explained above.
