The CW has released the official still images from next week’s episode of The Flash, titled “Elongated Journey Into Night”. You can see one image of Ralph Dibny (Hartley Sawyer) with Barry here at the left, and the rest of the stills can be viewed at Flash TV News. The episode will air on October 31st.

The CW has released the official synopsis for the fourth episode of the season, titled “Elongated Journey Into Night”. It’s due to air on Halloween, and the title gives a big clue about one of the guest stars in the episode.

The Flash: “Elongated Journey Into Night”
TOM CAVANAGH DIRECTS; DANNY TREJO GUEST STARS AS BREACHER — Cisco (Carlos Valdes) is shocked when Gypsy’s (guest star Jessica Camacho) father, Breacher (guest star Danny Trejo), shows up on Earth-1. Breacher takes an immediate disliking to Cisco and decides to hunt him. Meanwhile, Barry (Grant Gustin) runs into his old nemesis, Ralph Dibny (guest star Hartley Sawyer). Tom Cavanagh directed the episode written by Sterling Gates & Thomas Pound (404). Original airdate 10/31/2017.

CBR has a sneak peek at Breacher and Elongated Man from one of the teasers, which you can see here.

Plus, there’s word that the Kilg%re is one of the new villains we’ll be seeing this season. It will probably tie in with the Thinker somehow, who’s the major villain this season, although there’s no word on whether it will be one of his creations or some sort of associate.

Who’s looking forward to Ralph Dibny and the Kilg%re? How about seeing Danny Trejo in action? Share your thoughts here!
