From VancouverFilm.Net, Sneak Peek footage, plus images from "The Flash" episode "Null and Annoyed", directed by Kevin Smith, airing April 10, 2018 on The CW:
"...'Barry' (Grant Gustin) and 'Ralph' (Hartley Sawyer) take different approaches to finding the remaining 'metas' before 'DeVoe' gets to them. However, Ralph's cavalier attitude frustrates Barry and the two clash over what it means to be a hero. Meanwhile, 'Breacher' (Danny Trejo) returns to ask 'Cisco' (Carlos Valdes) for a favor..."
"I was working on 'Flash'", said Smith. "People are going to see it and be like 'You fucking jumped the shark with this.' There's some witty shit, and there's some visual jokes."
Smith also appears in the episode with his "Jay and Silent Bob" side-kick Jason Mewes.
"So I was like 'Oh fuck, I don’t wanna do it.' But I knew if I said no, I’d never hear the end of it from (Jay). Cause he'd go 'We had a chance to be on a fucking 'Flash' together, and you didn't fucking take it!' "
