CW Network TV series "The Flash" again aired a strong episode this time featuring a new villain. After battling Captain Cold and Heatwave, Barry Allen (Grant Gustin) took on Pied Piper (Andy Mientus) who used to be Dr. Harrison Wells' (Tom Cavanagh) prodigy named Harley Rathaway. Pied Piper proved to be a really difficult enemy as he found ways to escape STAR Labs' special prison after getting caught the first time. Still, the brilliance of The Flash and his colleagues is something the citizens can rely on. Although he is again in prison, Harley is not done yet and according to "The Flash" TV series spoiler from TV Line, his vengeance will happen in the next episode.
In an interview shortly after the last episode titled "The Sound of Fury" aired, executive producer Andrew Kreisberg shared some major "The Flash" TV series spoiler. One of which is about the future of Pied Piper and the weight of the threats he dropped on Cisco (Ramon Valdes) at the end of the night. As you can recall, the latest villain in Central City said he knew what happened to Caitlin Snow's fiancee Ronnie Raymond (Robbie Amell) and that knowledge of his is the reason why Cisco will unlock him out of prison. The answer to this will be found next episode.
"The repercussions of that will play out in the next episode," Kreisberg told TV Line.
"Caitlin's reaction to this information and also the knowledge that Cisco closed the door on Ronnie in the accelerator is both surprising and not at all surprising."
Aside from Piper, another thing that could bring trouble to the crew in the upcoming episode is the first thing they did at the star of the episode. (The Flash TV series spoiler here) The team took a selfie and although that seems a small thing, that would spell trouble for Barry in the next episode according to Kreisberg.
"Shockingly, that selfie - which, if it got into the wrong hands, could mean big trouble for Barry - will not rear its ugly head again. "We don't have any plans for that to bite us," Kreisberg admits."
