Kevin Smith began production on his second episode of "The Flash" today, teasing a title that may hint at the return of a certain icy metahuman. The title, which was strategically covered up a pen, could actually be seen through the page. Heroic Hollywood spotted the title, revealing it to be "Killer Frost."

The character of Killer Frost, Earth-2 Caitlin Snow, was killed by Zoom during season two, so how could she be coming back? As seen many times on superhero shows like "The Flash" and "Arrow," life finds a way, and it would appear that there is more to Earth-2 Caitlin's story.
Fans have long wondered if Earth-1 Caitlin (Danielle Panabaker) would ever turn into Killer Frost, but so far she has not exhibited any metahuman abilities. This title could be a misdirection or it could me metaphorical. It was announced earlier this year that Caitlin's mother was coming to show. Perhaps the title has more to do with the frosty relationship Caitlin has with her mother and less to do with the ice-wielding Earth-2 metahuman.
"The Flash" returns to The CW on Tuesday, October 4.
