Now that Flashpoint is happening the people at CW now have a chance to bring Supergirl into the 'Berlanti universe' and Stephen Amell said Flashpoint will affect Season 5 of Arrow, I can only conclude that it is going to be the same across all of the shows and they have also said that Supergirl will be the main focus of the crossover but Barry can't just bring everyone to her specific earth just for the crossover right? Thoughts?
