Homelander takes Ryan to visit the abandoned Vought lab where Ryan was born (via a breast milk bottle of his own mother’s milk, of course). The interesting part? Homelander genuinely tries to bond — but only by showing Ryan a preserved fetus of a failed Supe. He calls it Ryan’s “brother.” Ryan is visibly horrified. It’s a masterclass in showing Homelander’s complete inability to understand human emotion, while also revealing his loneliness.
The title “We’ll Keep the Red Flag Flying Here” is a lyric from the socialist anthem “The Red Flag.” This directly contrasts with Homelander’s growing fascist imagery (red, white & blue flags) and foreshadows the episode’s theme: regular people trying to keep hope alive under a fascist regime.
If you meant V P3 as in (like the promo clips from the Vought News Network on YouTube), let me know — those have different content (like a teaser about Tek Knight’s prison). Otherwise, Episode 3 of S4 is widely considered the season’s turning point. the boys s04 vp3
We learn why the right-wing Supe influencer Firecracker (Valorie Curry) hates Starlight. In a flashback, a young Annie (Starlight) accidentally caused Firecracker to be permanently injured during a childhood pageant. But the real interesting part?

For book readers and careful viewers: Butcher’s CIA ally Joe Kessler (Jeffrey Dean Morgan) is not real — or at least, not entirely. In Episode 3, Kessler gives Butcher advice while no one else acknowledges him. Later, Butcher takes a mysterious pill from Kessler that may be slowing his brain tumor… or feeding his hallucinations. The show hints Kessler is a hallucination born of Butcher’s guilt and Temps V side effects.

Black Noir (the new one) asks Sister Sage what her grand villain plan is. Her answer? “Fix the subway system.” She explains that if Vought can improve New York City’s infrastructure in visible, helpful ways, people will overlook the evil. It’s a biting satire of corporate “social good” campaigns. The internet loved how refreshingly mundane and plausible her evil genius is here.
