While said ‘Duet’ clip doesn’t feature any singing or dancing, the footage does show Team Flash members Vibe and Kid Flash joining forces with Martian Manhunter.
The next crossover for The CW’s ever-growing Arrowverse is a musical episode of The Flash that includes appearances by Supergirl‘s Kara, J’onn, Mon-El, and Winn.
‘Duet’ finds Kara and Barry under the spell of the Music Meister, who first appeared in last night’s Supergirl episode, ‘Star-Crossed’.
In Meister’s alternate reality, Kara and Barry will be caught up in a musical featuring some of The CW’s most accomplished singers.
