Both “Godspeed” and “Snow Pack” deal with Team Flash’s discovery that Nora (Jessica Parker Kennedy) has been working with the Reverse-Flash (Tom Cavanagh). Barry (Grant Gustin) doesn’t take the news well, and his reaction to returning Nora to her own time sets forth a series of events that strains his relationship with his wife and forces Nora even closer to Thawne and down a darker path. “Godspeed” fills in the gaps of Nora’s storyline offering a glimpse of her future life, and how the threat of a speedster and the discovery of her own powers lead her to seeking help from the Reverse-Flash. Although much of this information had been revealed to audiences, the news is still shocking to Barry and his friends with more detail provided about the timing of Nora’s discoveries and her return to the past.
With Grace Gibbons (Sarah Carter) mostly absent from both episodes, the focus of “Snow Pack” splits to continue the fallout of Nora’s bombshell and include a B-story featuring the return of Caitlin‘s (Danielle Panabaker) father who plans to reunite his family as reborn heartless ice warriors. After a brief moment of hope, the storyline ends tragically while also foreshadowing more frosty moments to come. While the episode teases the new Cicada making use of the technology Icicle (Kyle Secor) stole, more immeadiate for Flash and friends to deal with is the return of Nora who appears quite affected from traveling a darker path to return to the past and embracing Thawne’s version of the Speed Force.
