New photos from The Flash Season 7 set show Barry Allen's Flash battling enemies alongside his and Iris West's future children, Bart Allen's Impulse and Nora West-Allen's XS.The Flash will commemorate its 150th episode with a West-Allen family reunion, bringing Bart/Impulse into the Arrowverse while also welcoming Nora/XS back. Posted online by Canadagraphs, the series' latest set photos show Bart/Impulse in his comic book-accurate costume surrounded by six Godspeeds, prompting him to cower when they raise their arms up to attack. However, while the Godspeeds (confusingly) appear to leave him alone after that, things could easily play out differently during the actual episode. Either way, The Flash and Nora/XS arrive a moment later, pausing for a quick (mid-battle?) chat.RELATED: The Flash Has Officially Entered Its Old Yeller Phase

Jessica Parker Kennedy's Nora/XS was introduced in Season 4 as a mysterious young woman who kept crossing paths with Team Flash, including serving as a waitress at Barry and Iris' wedding. She eventually revealed her true identity in the Season 4 finale and went on to spend time with her parents in the present-day throughout the first half of Season 5. As it turned out, though, Nora/XS had secretly been manipulated by Barry's nemesis, Eobard Thawne, to run back in time as part of a scheme to break him out of prison in the future. And while she ended up helping Team Flash defeat Thawne and Cicada, this iteration of Nora/XS was erased from the timeline in the Season 5 finale.

For the time being, it's unclear if Nora/XS will remember any of this when she returns in The Flash's 150th episode, much less whether she's met her brother before. Jordan Fisher was announced to be playing Bart/Impulse in March and will appear as a recurring guest star in the second half of Season 7. His official description reads, "Bart is the fastest teenager on the planet! But due to Bart's penchant for wildly impulsive behavior, stunned parents Barry and Iris will have their hands full trying to teach their new son patience. But it's a task they'll have to accomplish, in order for their family to work together and stop Team Flash's biggest threat yet!"

The Flash stars Grant Gustin, Candice Patton, Jesse L. Martin, Danielle Panabaker, Carlos Valdes and Tom Cavanagh. New episodes air Tuesdays at 8 p.m. ET/PT on The CW.
