This clearly feels like a ratings stunt. I wonder if news of the Flash/Supergirl musical episode also convinced them to finally do one?
A ratings stunt and a check mark off the old “to do before we close up shop” list. Like, I actually believe that somewhere in the writer’s room there’s a list of “frequently asked about things” from the fandom and they’re just trying to tick off as many as they can: Rumple’s mother and the Black Fairy; the return of Tinkerbell; a musical episode. I know that S7 is almost a sure a thing but if it’s not a full 22 season then they need to check off things a little more quickly.
