21-22 is going to be the season (Not series) finale, and therefore will be a launchpoint to set up what we could get in Season 7. And if it follows the same path as previous season finales, there will be very little connection between the story of the Finale and the story/stories told in the regular season. So I don't see SAviorology or the Black Fairy carrying over to the Finale.

The Musical episode might carry over, though. The finales (at least the past couple of seasons) have been prone to try different ideas (Time Travel, Alternate Universe, etc).

So I"ll offer that 6x19 could wrap up Tiger Lily (since there is some supposition that she will be part of that episode), 6x20 will wrap up both the Black Fairy and Gideon/Saviorology (assuming one of these 2 arcs is not already wrapped up by that point). The 6x21/6x22 is Finale (possibly musical).
