Warning: The Flash series spoilers ahead. The last episode highlighted one big event on the life of Danielle Panabaker's Caitlin Snow. The episode featured Snow's fiancee, Ronnie Raymond (played by Robbie Amell) who disappeared after an explosion at S.T.A.R. Labs. That moment will shape Caitlin Snow's fate in the show. Meanwhile, another assistant of Dr. Harrison Wells (played by Tom Cavanagh) is yet to get his own moment. Carlos Valdes' Cisco Ramon, who is named after the civilian identity of Vibe, is someone who provides the laugh in the Flash series. In the next episode, things will get serious for him, especially after making a big mistake that will negatively affect Grant Gustin's Barry Allen.
According to the Flash series spoiler provided by the Entertainment Weekly's Inside TV, Cisco will learn a valuable lesson after making a mistake of creating a cold gun to slow down the Flash. That gun unfortunately ended up on the hands of Captain Cold (to be played by Wentworth Miller), one of the main villains that the Flash will battle.
"Cisco has this trajectory of growth," Valdes said of the upcoming the Flash series episode as per the EW. "Part of that growth involves his coming to terms with responsibility and what it means to be a hero and what it means to accept responsibility for the things that you've done. That episode is very important for Cisco in terms of learning the lessons of responsibility, especially when it comes to the people that he loves and the people that he cares about."
Another the Flash series spoiler that will make the next episode a must watch is about a visitor from Arrow, Emily Bett Rickards' Felicity Smoak. The episode, titled Going Rogue, is the first of at least a couple episodes that fans will see the cute nerd of Queen Consolidated interact with the gifted investigator from Central City. Rickards, along with Arrow himself Stephen Amell, will be part of two crossover episodes with the Flash series. Those episodes will air on the eighth of the Flash series and Arrow.
