Ever since it was announced that Supergirl was coming to the CW for its second season, speculation has been brewing about crossovers with other DC shows on the network. Supergirl has already crossed over with The Flash, so fans have begun wondering whether crossovers with Arrow or DC's Legends of Tomorrow are far behind. Shortly after The CW announced their Fall 2016 schedule, the network also promised a big four-way crossover in which all of the superheroes join forces for a major event.
At a recent event, Arrow star Stephen Amell discussed how he thinks the massive crossover will take shape as well as the one thing that he really wants to see when Supergirl and Arrow finally meet.
Speaking at a panel at Wizard World Philadelphia, Amell talked about how unique the situation with the CW's DC shows is and how he envisions the massive crossover coming together. According to ComicBook.com, Amell described it as being a single four-night event that spanned all four shows. Amell also addressed the fact that Supergirl currently takes place on a different Earth:
"I think what we'll end up seeing is one giant four-night crossover. No seriously. [Much applause] How we're going to end up doing that... I don't know. But, this is kind of an unprecedented moment in terms of the history of network television. To have four shows, same showrunner. Obviously Supergirl is in a little bit of a different universe, but we can fix that. That's one line of dialogue and it's all fixed. So I would suspect Oliver will be meeting Supergirl at some point."
Amell further elaborated on a possible Arrow/Supergirl crossover, describing the main thing that he wants to see happen if or when it finally occurs. According to Amell:
"All I want to see is Supergirl fly and David Ramsey's reaction to it. That's really all we want to see. And I'm still mad I haven't shared a scene with Victor Garber yet, so as long as that ends up happening I'll be good."
Certainly, it will be interesting to see how such a crossover comes together. Given the events of the season finale of The Flash, the third season of the show will probably have a decent amount of story to go through before such a crossover would fit in naturally. Likewise with Supergirl; despite Amell's claim that it would just take "one line of dialogue" to bring Supergirl into the standard Arrowverse, fans can likely expect the first part of the second season to deal with bringing the two universes together. But, CW head Mark Pedowitz previously said the crossover will arrive in December, as have the previous events.
Some fans might prefer if the shows focused on their own storylines for a while, but so long as the crossover occurs organically within the shows and doesn't seem forced, it's unlikely that too many fans will be upset. This is especially true once you consider the size of the threat that would be required to bring the heroes of all four shows together to fight it. The crossover could set up new plot points in each of the shows, and with any luck might also leave Diggle believing that a girl can fly.
Supergirl season 2 will air at 8pm Mondays on The CW in Fall 2016, The Flash will air in the same timeslot on Tuesdays, Arrow on Wednesdays, and Legends of Tomorrow on Thursdays.
