Warning: The following contains spoilers for Flash #774, on sale now from DC.
The Flash Family extends across space and time, reaching across generations of speedsters. For a good period of time, even Wally West's children, Jai and Iris "Irey" West, became superheroes, and in Flash #774 (by Jeremy Adams, Christian Duce, Hi-Fi and Steve Wands), it appears that Irey is ready to reenter the superhero game.
In this issue, Irey and her father stumble upon a plot by Doctor Nightmare, who has put many of Central City's citizens into a deep sleep. Nightmare has also used his technology to bring people's nightmares to life, which he uses to rob Terrifitech. Showing great bravery, Irey insists that she join Wally in his efforts to stop Doctor Nightmare.
Considering her age, Irey shows a lot of courage by joining her father on this particular mission. Several moments highlight Irey's heroism, including one scene where she rushes to take Doctor Nightmare's device away from him while he isn't looking. Considering neither Irey nor Wally have their speed at the present, this is a massive risk for her.
More impressively, Irey comes up with a big idea that saves the day. When Wally is beginning to consider calling the Justice League, Irey has a plan of her own. She decides to use the nightmare helmet on herself, conjuring her own dreams to counter the constructs of Nightmare. The outlandish creations from Irey's dreams end up winning the day, rendering Doctor Nightmare helpless and defeated.
In a way, Irey not only saves Terrifitech from a robbery, but she also she saves countless citizens of Central City as well. This shows a lot of courage and heroism to say the least, especially considering the fact that she has no powers yet, and her father's abilities had been neutralized.
The fact that Irey would still choose to run in and fight Doctor Nightmare is a true testament to her bravery. Of course, it's not surprising that Irey would demonstrate such heroism. Pre-"Flashpoint," Irey and her brother, Jai, were superheroes. Irey even took the name "Impulse," a name previously used by Bart Allen.
Several times in this issue, Irey quotes her father, demonstrating the lessons that he's bestowed upon his kids. Irey notes that this adventure will be a "good learning experience" and that "Wests save the day," statements with which Wally can't argue. Heroism truly runs in the West family.
All of Irey's heroic traits hold great promise for her future. This future has been teased before, in 2021's Flash #771 (by Jeremy Adams, Kevin Maguire, Howard Porter, and others). In this issue, Wally landed twenty years in the future, landing in his son Jai's future body and meeting an adult version of his daughter. In this future, both Jai and Irey were revealed to be superheroes, following in Wally's footsteps. Irey was so experienced by this point that Wally's sudden appearance didn't even surprise her.
Irey told Wally all about how he taught both of his kids to be a hero. Moreover, Irey was revealed to be stronger in the Speed Force than anyone before her. In Flash #774, it seems that Irey is now taking her first steps into becoming the hero she is destined to become.
