SPOILER WARNING: This article contains major spoilers for "Snow Pack," the latest episode of The Flash.
Nora West-Allen just took a villainous turn. In "Snow Pack," the latest episode of The Flash, she begged Eobard Thawne for a way to get back to 2019 without her father Barry's notice. He obliged, but his method may send her down a dark path.
When Barry dropped Nora off in her timeline, he warned her not to come back. Before he left, he curtly informed her that he could sense when she entered the Speed Force and would turn her right around if she attempted to return. Desperate, she sought out Thawne for advice, seeing as the Flash -- nor any other speedster -- never had the ability to see him coming like that.
Though at first he told her "it isn't for you," he relented and explained that he created his own Speed Force to travel through time. "So instead of tapping into the Speed Force to access my powers, I created my own," he explained. "I have to warn you, Nora. It's a little bit negative."
"Negative" may be putting it lightly. Per his instructions, Thawne's method of tapping into this Negative Speed Force relies on rage and pain. "You're reaching out and nobody's there. The loneliness is pain -- pain racing through your mind, crushing you, wrecking you, shattering your soul into a million little pieces," he said. "And suddenly, you are no longer you. You're part of something different now, part of a negative force."
Though he attempted to walk her through it, Nora was unable to enter the Negative Speed Force. When she demanded to know why she couldn't, he replied, "Listen, not harboring enough rage to fuel your trip is nothing to be ashamed of. You're just like your father. Your light is your greatest strength."
Nora managed to find her rage when her mother Iris arrived in the future to take her back to 2019. "Do you know what it's like to want something more than anything else in your whole life?" she spat. "To know your father? To do your best to follow in his footsteps? To make him proud? How could he leave me? How could he stop loving me?" With that, she took off running and entered the Negative Speed Force, where she relived some of her worst memories.
When Nora reemerged, she was transformed. The Speed Force lightning pulsing through her skin now included red -- Reverse-Flash's signature color. Worse, her eyes had turned red as well, indicating that she had fully embraced her rage and the Negative Speed Force.
In the comics, Reverse-Flash does indeed use the Negative Speed Force to travel in a way other speedsters can't detect. Negative Speed Force has the ability to corrupt regular Speed Force, which changes the way speedsters operate; for instance, when Barry was infected, his metabolism was slower and he took longer to heal from injuries. Worse, it enhanced his rage and the destructive capabilities of his powers.
If The CW's The Flash borrows from the comics, that means Nora has embraced a villainous path whether she realizes it or not. The Negative Speed Force, which has physically altered her, is sure to feed off her rage. Like Reverse-Flash points out, it will take Barry and Iris combined to get their daughter out of this mess.
Airing Tuesdays at 8 p.m. ET/PT on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanaugh, Jesse L. Martin, Danielle Nicolet, Hartley Sawyer and Jessica Parker Kennedy.
