‘Supergirl’ episode 18 reaction: Could another crossover with ‘Arrow,’ ‘The Flash’ happen?

We’re starting to get a sense of what the precise reaction is to the big appearance of Barry Allen on “Supergirl,” and there is one word to describe it: Glee, and not that one show that Grant Gustin and Melissa Benoist were on. Everyone seems for the most part to be very much pleased with how things turned out here.

So could we have something more soon in the crossover department? While executive producer Greg Berlanti made it clear (per TVLine) that it’s not happening again right away, this is something that he’d be thrilled to include in the future:

“From the day we cast Melissa [Benoist], the notion of her in scenes with Grant [Gustin] – or someday maybe in the best of all worlds with [Arrow star] Stephen [Amell], as well – it’s exciting to think of them on screen together.”

Of course, we know that there are massive logistical issues that make things difficult; heck, they were difficult this time. You’re dealing with two separate networks, as many as four shows if you include “Arrow” and “Legends of Tomorrow,” and “Supergirl” films in a different city than the rest of them. This makes it rather difficult sometimes to sort everything out. Also, the show has a huge challenge given the fact that the world in which National City has Supergirl is a different world than the one where Barry Allen is running around saving people as The Flash. It’s not so easy for someone like Oliver Queen to just run up to her and wave “hello.” There are more challenges getting him to cross paths with her.

Ultimately, we will be excited to see what the writers come up with for the future.
