Now, new photos from the set of The Flash’s episode may offer insight about one aspect of the musical crossover episode.
However, another event-style crossover is planned for two of The CW’s DC Comics-based series with The Flash and Supergirl teaming for a musical episode later this season.
Although it’s unclear how these new set photos fit into the plot of ‘Duet’, it seems clear the episode will offer fans of The Flash and Supergirl more than even its musical numbers.
Until then, fans of The Flash and Supergirl have plenty to look forward to when the heroes team up in their first musical crossover event.
