'The Flash' Season 4: Barry Allen Is Getting A Bacheclor Party Before He Weds Iris

After hopelessly crushing on his childhood best friend for years, Barry Allen (Grant Gustin) will finally wed the woman of his dreams Iris West (Candice Patton) in "The Flash" Season 4. Their lives might not be normal but like any husbands-to-be, the Scarlet Speedster is getting a bachelor's party. 

Barry and Iris finally got engaged last season and, earlier this year, show executive producer Andrew Kreisberg confirmed that the two will tie the knot in the upcoming season. Despite all the chaos happening in Central City, the wedding is still on and, in fact, they are getting a bachelor and bachelorette parties. 

According to EW, the episode titled "Girl's Night Out" will see well, the girls hit the town to celebrate the engagement. "Arrow" star Emily Bett Rickards will even pop up as Felicity Smoak to toast the upcoming wedding of Iris and Barry. Dr. Caitlin Snow (Danielle Panabaker) is also expected to be invited.

Barry, too, will forget his duties as the Scarlet Speedster for a few seconds and party the night away. Cisco (Carlos Valdes) has laid out plans to celebrate his friend's "last night of freedom."

However, things will not exactly work out as planned and, according to the report, the stag party will go awry. Perhaps, the title of the episode was not alluding to Iris' bachelorette party all along. 

Does new villain Amunet Black a.k.a. Blacksmith crash the party? The DC Comics baddie played by Katee Sackhoff ("Battlestar Galactica" is expected to make her television debut in "The Flash" Season 4 Episode 5 ("Girls Night Out"), as reported by Collider. 

The Blacksmith was first introduced in the comic book-verse in 2001. She has the ability to reshape metal and merge organic and inorganic matter. 

"The Flash" Season 4 will premiere on Oct. 10 on The CW. Watch the trailer below.
