The cast of heroes slated to appear in the crossover will include characters from Supergirl and Legends of Tomorrow in addition to The Flash and Arrow, however.
We’ll have to wait and see how much of a role Thea will have as Speedy in the massive 4-part crossover.
So many people on screen could mean that Thea might not get too much time in the spotlight in the crossover event.
Thea has more experience and a more intense training background than any of the newbies.
