It may seem like an odd question, but it's one being posed more and more frequently by those skeptical of DC Comics' TV plans: what good is a half-dozen superhero shows if they don't connect to one another? DC and Warner Bros. only have themselves to blame for the debate, with Arrow first adding The Flash as another branch of the same shared CW universe. Given the success of both, networks lined up to get in on the action - and WB was all too eager to please.

Fox claimed Gotham - minus the Dark Knight, of course - and NBC took the horror route with Constantine, but eyebrows were raised when Supergirl was handed to CBS - and therefore would not be included in the same universe as the other two costumed Justice Leaguers. As superhero team-are becoming the new normal, could DC and Warner Bros. really have no intention of putting Green Arrow, The Flash and Supergirl on the same screen?

That question has proven a difficult one to answer. For starters, Greg Berlanti is acting as executive producer of all three shows. Secondly, both Warner Bros. and CBS have a stake in The CW, meaning that a ratings-boosting crossover (all but a guarantee) could benefit both. Even so, concrete answers or statements of intent on Berlanti or the networks' part have been scarce.

Speaking during Fan Days at Dallas Comic Con (via ComicBook.com), Arrow star Stephen Amell was asked about his own thoughts on potential crossovers. Claiming that working with John Constantine could be interesting given the mystical Lazarus Pits introduced this season, it was no surprise to see Amell connecting the same Supergirl threads as the fans:

"It would be cool to crossover with Supergirl because it's something with Greg Berlanti, who's the helmer and sort of the brain trust or the center of the brain trust of Arrow and The Flash and I know so many of the people that are involved in the production of that show so that would be really interesting."

Though Amell is clearly drawing the same conclusions as most viewers, his lack of a real tease is telling. After all, this is the same actor who claimed that The CW was already creating a Justice League on TV, and that Flash star Grant Gustin should be playing the hero on the big screen. To say that a crossover with Supergirl would be merely "cool" or "interesting" implies that he has little insider knowledge.

That's not good news or bad for those wishing to see Supergirl (Melissa Benoist) opposite Barry Allen, merely a reality check. Amell, like those at CBS, The CW, and Berlanti himself seem determined to take things slow. The early success of The Flash is what made a crossover event such an appealing idea, so if Supergirl gets off to as strong a start, then perhaps more crossover talks can take place.

As for Gotham, well, Amell seems torn between practicality and a desire to make the most of DC's movie/TV multiverse:

"Gotham would be a tough one, just because I think they're out in a different time but the crossover with The Flash was so much fun and did so well that I can't imagine a world -- a universe, no pun intended -- where that didn't happen and continue to happen all the time."

What do you think of Amell's comments? Does a joint adventure between Supergirl and at least The Flash seem like a matter of time, or do you have concerns? Sound off in the comments.

Arrow airs Wednesdays @8pm on The CW. Supergirl is expected to air on CBS in 2015.
