"The Flash" Season 1, Episode 10 is going to feature a big villain, who is teaming up with another DC Comics character. There is no new episode this week, giving The CW fans ample time to ponder the events of Episode 9 ("The Man in the Yellow Suit") and speculate about what happens next to Barry Allen (Grant Gustin).

Realizing the Reverse Flash is much faster than he is, Barry Allen begins pushing himself harder. He also has to deal with the new Iris West (Candice Patton) situation. And in the next episode, he has to face two big villains. When The Flash returns in 2015, Barry Allen is not likely to catch a break.

"The biggest thing [in The Flash Season 1, Episode 10 is the team-up of] Captain Cold and Heat Wave. We have a 'Prison Break' reunion with Dominic Purcell and Wentworth Miller," The Flash showrunner Andrew Kreisberg recently told the Hollywood Reporter.

"As Barry is struggling to train his speed in order to beat Reverse Flash, his old friend, Captain Cold, returns to Central City with the help of a new villain, Heat Wave," reads the episode synopsis of The Flash 1x10 on IMDB.
