‘The Flash,’ ‘Legends Of Tomorrow’ Crossover: Wally Helps Nate Defeat Bad Guys

Fans won’t have to wait until November to see some crossover episodes between CW’s DC TV series.

In DC TV’s recently released “Save the Day” promo, which teases the much awaited returns of “Arrow,” “The Flash,” “Supergirl” and “Legends of Tomorrow,” Wally (Keiynan Lonsdale) is seen bantering with Nate (Nick Zano) after putting all the bad guys down.

“Damn it Wally, what’d I say?” asks a disappointed Nate.

“I was supposed to save the bad guys for you,” replies Kid Flash.

“Just a few,” Nate clarifies.

Elsewhere in the promo, a date night between Alex (Chyler Leigh) and Maggie (Floriana Lima) is interrupted by work, prompting the DEO agent to say that from now on, she’ll only be doing date night in tactical gear.

Meanwhile, Sara (Caity Lotz) and Ray (Brandon Routh) are seen facing off against Roman soldiers, and towards the end of video, Cisco (Carlos Valdes) happily proclaims, “We back baby,” after Team Flash is apparently reunited with Barry (Grant Gustin) following his stint in the Speed Force.

Aside from the mini crossover between “The Flash” and “Legends of Tomorrow” revealed in the promo, it was also announced earlier this week that “Arrow” star Emily Bett Rickards will be popping up as Felicity in Season 4, episode 5 of “The Flash” for a girls’ night out.

As for this year’s big four-way crossover, Arrowverse executive producer Marc Guggenheim previously revealed that they will be trying to outdo last year’s “Invasion!” by increasing the emotional stakes.

“Every year we feel the pressure [to top ourselves],” Guggenheim told Entertainment Weekly. “I feel like each crossover has topped the previous one. [But] topping last year’s, that’s a high bar. … What do you do that’s bigger than aliens? We’ve got some very, very exciting ideas. … Very early on in the process of doing last year’s crossover, [executive producer] Greg [Berlanti] said there’s probably no way to get bigger than aliens, so the best way to make the [next] crossover especially epic is if you can’t increase the bombast, increase the emotional stakes and the emotional payoffs, so that’s a very oblique comment on where our heads are at for this season.”

This year’s crossover will only be a two-night event. It will kick off on Monday, Nov. 27 at 8 p.m. EST with “Supergirl,” followed by a special Monday episode of “Arrow” at 9 p.m. The special programming block will continue the following day, Tuesday, Nov. 28, with “The Flash” and “Legends of Tomorrow” in their regular time slots, 8 p.m. and 9 p.m., respectively.
