The tacked on at the end of an episode of Supergirl nature of crossovers with the rest of the Arrowverse is annoying, but actually kind of works due to the relatively self-contained and distinctive nature of Supergirl in comparison with the rest of the Arrowverse.

As soon as they announced a musical crossover and I became aware of the Glee connection between Grant and Melissa, I saw at the very least a mini Glee reunion coming from a light year away.
