The Flash Season 3: 12 Things You Need To Know

3. Sing-A-Long

Not only are we being treated to a four-show crossover in December (bringing together Arrow, The Flash, DC’s Legends of Tomorrow, and Supergirl), but Grant Gustin’s Scarlet Speedster is having a musical crossover with Melissa Benoist’s Supergirl.

And yes, you did read that right.

In fairness, both Gustin and Benoist made names for themselves in Glee, so they’ve both got the chops to belt out a tune or two. Added to that, the chemistry between the pair was as cute as an online cat video when The Flash turned up in an episode of Supergirl last season. Still, the concept of a musical crossover episode is something that took many by surprise when it was announced.

How do you get two superheroes to start bursting out in to song, though? Why, you bring in a musical-themed villain, of course. Step forward, Music Meister. The all-singing rogue will be front-and-centre for this crossover, with his antics being what leads to our heroes knocking out a song or two.

Additionally, the likes of Jesse L. Martin and Carlos Valdes both have musical backgrounds too, so don’t expect the singing to be restricted to just the Sultan of Speed and the Maid of Might.
