Warning: Spoilers ahead for Doctor Who season 14, episode 2, "The Devil's Chord."

Summary

• The Doctor faces a musical showdown in Doctor Who with Maestro, who has immense musical powers.
• Maestro's lingering aura causes a highly-choreographed song and dance number among characters.
• The musical sequence in the episode suggests Maestro's power sures the Toymaker's as it impacts reality to a greater degree post-defeat.

The ending of Doctor Who season 14, episode 2, "The Devil's Chord," is more akin to a Broadway musical than a science-fiction TV show, but the musical finale isn't as random as it initially seems. The Doctor and Ruby have an unconventional battle to face in the episode, the fallout of which has a strange impact on the story's closing minutes. The finale sequence is in keeping with the installment's musical elements, but the explanation goes beyond simple thematic relevance.

"The Devil's Chord" introduces Jinkx Monsoon to the Doctor Who's Pantheon - an order of immortal beings who come from outside the universe. Known as Maestro, the child of Neil Patrick Harris Toymaker falls to the Doctor with the assistance of Ruby Sunday and two fictionalized of The Beatles. The high-stakes clash between Maestro and the Doctor is the episode's climax, but that doesn't stop the story from including one last hurrah as it draws to a close.

Doctor Who's 1960s Closing Number Was Likely Caused By Maestro's Lingering Domain

Jinkx Monsoon's character has immense musical powers

At the bi-generated Time Lords. Applying the same logic to Maestro, the Toymaker's offpspring, and the impromptu group performance at the end of "The Devil's Chord" could have inadvertently been caused by Maestro's remaining aura after their defeat.

The Doctor describes Maestro as "The essence of music itself," so it would make sense that the remainder of the villain's power would influence the episode's characters in such a way.

The Doctor describes Maestro as "The essence of music itself," so it would make sense that the remainder of the villain's power would influence the episode's characters in such a way. Just as the Toymaker had already been defeated when Fifteen doubled the TARDIS, Maestro has already been vanquished when the characters in "The Devil's Chord" start performing "There's Always a Twist at the End." So, it would appear that Pantheon are so powerful, that their abilities continue to influence reality even after they fall - even if only temporarily.

Doctor Who Season 14, Episode 2's Musical Sequence Suggests Maestro Is Stronger Than The Toymaker

Maestro's influence on reality after being banished was far more pronounced than the Toymaker's

When the Doctors cash in on their victory against the Toymaker in "The Giggle," nothing is actively happening until they realize there is still a reward to be had. In other words, the Toymaker's domain was still present, but it wasn't detectable. When Maestro is defeated, those nearby seem uncontrollably sucked into a highly-choreographed song and dance number, meaning even Maestro's residual power sured that of their father in Doctor Who.
