Ever since it was announced Supergirl would make the jump from CBS to The CW, fans have wondered when she would appear on screen along with fellow DC TV heroes from Arrow, The Flash, and Legends of Tomorrow.
The CW kicked off the four-show crossover on Monday of this week with a short sequence at the end of Supergirl’s episode, ‘Medusa’, but the action truly began with The Flash on Tuesday, continued through Arrow on Wednesday and concluded in Legends of Tomorrow.
The CW president Mark Pedowitz was quick to assure fans there would be a massive four-show crossover, and that three-hour event completed tonight with the debut of Legends of Tomorrow’s latest episode, ‘Invasion!’
In respect to the cousin line, basically it’s sort of like [what] we did last year on Legends.
