Supergirl is coming to the Arrowverse, but don’t expect a full crossover episode

As the days tick down toward the fall premieres of Arrow, The Flash, and DC’s Legends of Tomorrow, and the Supergirl move from CBS to The CW, there’s one event that’s on the minds of fans everywhere: the crossover.

No sooner was it announced that Supergirl would be making the move to The CW, than reports of a four-show crossover were confirmed. The Flash did make a one-episode appearance on Supergirl last season, but a massive event between all four shows is another animal altogether.

Just yesterday, a Comic-Con interview with Arrow executive producer Wendy Mericle revealed producers’ “loose” plan for the crossover. “Yes we [have a loose plan] for the crossover. It’s loose, but we know that it will go in order for the week, you know, Supergirl [Monday], Flash [Tuesday], Arrow [Wednesday],Legends [Thursday]. That’s the loose plan right now.”

Now, fellow executive producer Marc Guggenheim has given some additional details on exactly how the crossover will work. The comments surfaced in a Comic-Con interview with Slashfilm alongside Legends of Tomorrow producer Phil Klemmer.

“It’s an external threat from outside the shows that will involve Supergirl coming over to Flash, then Arrow then Legends of Tomorrow,” said Guggenheim. “I don’t like to oversell. She is going to be coming over but we’re not going to do a full on Supergirl crossover episode. I don’t want to give you the wrong impression.”

While this may be disappointing to some people, it makes the most sense and was (at least for us) assumed to be the way the crossover would proceed. Supergirl is the one show that doesn’t exist in the same universe as the other three shows, so it’s logical to have her come to the Arrowverse, rather than the other way around.

So, as much as we’d love to see John Diggle, Oliver Queen, and others traipsing around National City, it seems we’ll have to wait for that moment, if it ever happens.
