We’re also expecting Jensen Ackles to make a return as Soldier Boy. Kripke previously told Entertainment Tonight: “The old TV adage is like, never kill anyone unless you really, really have to. Never close a door, open a window. We’ll all have to wait and see, but I can’t imagine the series ending without Soldier Boy making another appearance.”

While speaking to ComicBook about how Starlight is settling in to The Boys, Moriarty didn’t give too much away, stating: “Oh my God, okay I’m sorry it’s just, maybe this is just a good advertisement for Season 4, that I can’t answer that without maintaining composure. I can’t! No that’s my earnest response! I’m actually scared to answer… She is adjusting great.”

Nathan Mitchell’s Black Noir was killed off in the Season 3 finale, with Homelander ripping his insides out after he didn’t tell him about Soldier Boy. Maeve and Soldier Boy are both presumed dead to the public, when the former is actually living off the grid with her partner, while the latter is locked away by the government.

Cameron Crovetti, who plays Homelander’s son Ryan, has been bumped up to a series regular for Season 4. We’ve also got some new additions with Valorie Curry’s Firecracker and Susan Heyward’s Sister Sage – neither of whom have any origins in the comics.

And, as per Deadline, The Boys is welcoming another Winchester to the mix: Jeffrey Dean Morgan has officially joined The Boys Season 4 cast as a recurring guest star.

In an interview with E! News, Kripke said: “Jeffrey Dean Morgan is a superfan of the show, so he and I are talking.

“We’re trying to figure out something for Season 4. Nothing finalized yet, but he and I are chatting and e-mailing and seeing if we can make it work with his busy schedule. So, stay tuned on that.”

Prime Video shared two photos from the upcoming season of The Boys – showing off two new characters in their full suits. Susan Heyward’s Sister Sage and Valorie Curry’s Firecracker are both rocking their very own look. As per The Boys’ official Twitter page, Sage is “already a thousand steps ahead of you,” while “Firecracker has a short fuse.”

Simon Pegg will return as Hugh Campbell Sr., after appearing in just five episodes of Season 1 before vanishing in Season 2 and re-appearing in the opener of Season 3.

He’ll be joined by Black Mirror star Rosemarie DeWitt as Hughie’s mother, a character who’s never been seen in the show so far. Supernatural’s Rob Benedict and Once Upon a Time’s Elliot Knight have also joined the cast in undisclosed roles.

And then there’s the stars of Gen V. We know Maddie Phillips and Asa Germann will reprise their roles as Cate and Sam respectively, given the events of the spinoff, but it’s unclear if we’ll see Jaz Sinclair (Marie), Chance Perdomo (Andre), Lizze Broadway (Emma), Derek Luh (Jordan), and London Thor (also Jordan).
