Welcome to The Hollywood Reporter's weekly DC TV Watch, a rundown of all things DC Comics on TV. Every Friday, we round up the major twists, epic fights, new mysteries and anything else that goes down on The CW's Arrow, The Flash, Legends of Tomorrow and Supergirl and Fox's Gotham. While all the DC TV shows are on summer hiatus, THR breaks down all the latest news heading into their returns in the fall.

Four shows and a wedding? | Before getting into your regularly scheduled DC TV Watch programming, it's time for some crossover speculation: Is this fall's massive four-show, four-episode crossover about a wedding? At the 2017 Summer TCA press tour, The CW President Mark Pedowitz revealed that "romance is in the air" for the crossover event, and executive producers Greg Berlanti and Marc Guggenheim elaborated beyond that, explaining that going bigger than an alien invasion meant going "personal" and that "it's a big life event for a few different people" on the shows. With two main couples from Arrow and The Flash going through major changes heading into the new seasons, could Oliver (Stephen Amell) and Felicity (Emily Bett Rickards) finally take that next step and tie the knot, or will it be Barry (Grant Gustin) and Iris (Candice Patton), who just need to reunite in order to finally have their nuptials? Or could it perhaps even be a double wedding? There's only so long that The CW series can each stretch these engagements before paying them off, and that would certainly give the next crossover a lot of heart.

Legends of Tomorrow

Getting political | The addition of new Legends team member Zari (Tala Ashe) from the dystopian future will allow the series to get topically political in a way they haven't before. "You might have heard there was this election," executive producer Marc Guggenheim said. "Not to get political, but something we all gravitated toward in the writers room was the idea of the character being Muslim. That was very important to us." And the reason why Zari's DC Comics alter ego name Isis won't be used on the show also comes down to the current political climate. "It's pretty simple, really," said Guggenheim. "You might have heard, there is this terrorist organization called ISIS, and they're ruining things out there in the world. We just didn't want the baggage, quite frankly, especially given the fact that we are doing a Muslim superhero; it was just like opening up a can of worms. It's just not worth it."

Finding their purpose | As for what the major theme of season three will be, executive producer Phil Klemmer revealed that the Legends are going to be doing a bit of soul searching. "Last year we were the only sheriff in town as far as fixing time," Klemmer said. "The conceit of season two is that Rip [Arthur Darvill] has created this gigantic Time Bureau of professionals who have effectively replaced us or made us, at least on the face of things, obsolete. And it's these guys trying to find their purpose, because it's not like, at least in the beginning, they have to save the world. It's a much more personal story about them realizing that they need each other. There's a real love, and to me, the heartbreaking, bittersweet part of the story is where else do you fit in in this world? You've spent so much time traveling through time creating these bonds with each other. Though [they'd] never admit it, [they're] the only family [they] have."
