Folks,
CBS has ruled out, for now, crossovers between Supergirl and Flash and Green Arrow.
However thee producers of the three shows have introduced the Multiverse to their Flash 'verse and have Jay Garrick the Flash of Earth 2 visiting.
And are holding out the hope of crossovers with Supergirl using the Multiverse as a way to allow it.
So how about a crossover of the Flash, Green Arrow or Supergirl with Lois & Clark?
