The CW's The Flash is taking a four-week break following the end of Season 4's most recent episode, "Run, Iris, Run," and will return on Tuesday, April 10 at 8 p.m. ET/PT.
Following the model set by previous seasons, Season 4 has already taken two breaks: one from Dec. 5 to Jan. 16, which was part of the series' annual midseason break; and the other from Feb. 6 to Feb. 27, which coincided with this year's Winter Olympics in PyeongChang. Danielle Panabaker, who plays Caitlin Snow/Killer Frost on the show, tweeted out the return date and described the next episode as "worth the wait."
Hope you enjoyed last night’s episode of @CW_TheFlash ! We are on a break until April 10, but I think it will be worth the wait!— Danielle Panabaker (@dpanabaker) March 14, 2018
The first episode after the break, titled "Null and Annoyed," will mark the third episode that Kevin Smith has directed for the series. "Null and Annoyed" will feature both Smith and his frequent collaborator Jason Mewes cameoing as security guards. Mewes previously appeared in Smith's first Flash episode, Season 2's "The Runaway Dinosaur." Smith, who has been a key director for the Arrowverse, also directed the Flash Season 3 episode "Killer Frost" and has already helmed three episodes of CW's Supergirl.
"Run, Iris, Run" left Team Flash on an upswing after a series of losses to season villain Clifford DeVoe, aka The Thinker, with Harry Wells and Cisco Ramon creating and using a thinking cap of their own to identify the two remaining bus metas as Janet Petty and Edwin Gauss.
The teaser for Smith's episode seems to indicate that Team Flash will encounter a metahuman with the ability to manipulate gravity, which matches up with the abilities of Null in the comics. The episode's title, "Null and Annoyed," also hints at the character's debut. Although it's not confirmed at this time, it seems likely that Petty and Null are one and the same. Expect Null to stick around for awhile, as character breakdowns indicate that the role is recurring.
There are a lot of potential avenues that the show might take as Season 4 heads into its final stretch. "Run, Iris, Run" introduced Matthew Kim, a meta with the ability to transfer powers between people. He could end up being the key to finally defeating DeVoe, provided he doesn't get absorbed like every other bus meta, save for Ralph Dibny.
The appearance of Gauss -- known in the comics as Folded Man -- also opens up a lot of possibilities for the plot going forward. The team recently discovered that DeVoe was hiding in a pocket dimension, and Folded Man's abilities in the comics include travelling between the second, third and fourth dimensions and opening portals. Although he accomplishes that with the aid of a suit in the comics, it seems possible that the show might tweak his abilities a bit to suit its own needs.
Returning Tuesday, April 10 at 8 p.m. ET/PT on The CW, The Flash stars Grant Gustin as Barry Allen, Carlos Valdes as Cisco Ramon, Danielle Panabaker as Caitlin Snow, Candice Patton as Iris West, Jesse L. Martin as Joe West, and Tom Cavanagh as Harry Wells, with guest appearances from Keiynan Lonsdale as Wally West and Hartley Sawyer as the Elongated Man.
