Miss Scarlet Season 6 trailer teases Eliza and Blake’s evolving relationship in the PBS drama

The buzz around PBS’s Miss Scarlet Season 6 is real. The upcoming season drops for streaming on December 7, 2025, and hits TV screens January 11, 2026.

The latest trailer gives us a peek at Eliza Scarlet (Kate Phillips) and Inspector Alexander Blake (Tom Durant-Pritchard), and their relationship looks more tangled than ever. They have always had a rocky partnership, but now it’s shifting, maybe into something a little more trusting, maybe even romantic, all while they chase down criminals in Victorian London.

This season isn’t just about the cases, though. Eliza’s detective agency is thriving, but her personal life is a fresh ground. She is figuring out how to juggle her work with her feelings, especially since romance isn’t exactly her comfort zone. You will see her stumble and learn, especially around Blake, and that tension between them isn’t going anywhere.

Old favorites like Ivy and Mr. Potts are back, now settling into married life, and there is a mix of new and familiar faces at Scotland Yard. Miss Scarlet still nails the period details, but this time, the emotional stakes feel higher.

Miss Scarlet Season 6 trailer: Eliza and Blake’s evolving relationship

PBS teases Miss Scarlet Season 6 with one big question: “Can Eliza have it all?” That is the heart of the story this time: her drive at work, her hopes for her personal life, all tangled together.

Here is how Miss Scarlet Season 6 shapes up: Eliza and Blake’s rocky partnership starts to shift. They are trying to work together now, but it is anything but simple. There is tension, awkwardness, maybe even sparks. At the same time, we see Ivy and Potts figuring out married life, a new detective settling into Scotland Yard, and Nash stirring up trouble from far away. So, a lot is going on.

The first-look photos say plenty. Eliza and Blake side by side, diving into cases, swapping documents, hanging around Scotland Yard. Their teamwork feels like the season’s main thread.

If you have watched earlier seasons, you know Eliza has worked with a few Yard regulars, especially William “The Duke” Wellington. But last season, Alexander Blake (played by Tom Durant-Pritchard) stepped in as the new inspector. Blake doesn’t exactly roll out the welcome mat for private detectives like Eliza. He has his reasons: bad history with PIs, a general reluctance to let outsiders in.

But then, the Season 5 finale changes everything. Eliza shows up at Blake’s door with cake. He invites her in to meet his daughter. There is this moment at the door, some real electricity between them, and it’s clear that Eliza is tired of going it alone.

So, that’s where Miss Scarlet Season 6 picks up: Eliza and Blake, still bickering, still drawn to each other, with a partnership that is growing into something deeper. The earlier seasons built up to this. Now, we see where it goes.

The official logline for Miss Scarlet Season 6 states:

“As Eliza and Blake’s once-fraught relationship begins to evolve, they find that working together may be a tricky prospect.”

According to PBS cast/creator commentary, Kate Phillips (Eliza) says:

“I think professionally, she’s gone from strength to strength, but emotionally, I think she’s got a lot to learn, and I hope there’s more joy to be had in her personal life.”

Meanwhile, Tom Durant-Pritchard (Blake) says:

“When we get to Season 6, I’m looking forward to seeing where his relationship with Eliza ends up. Because we leave them at the end of Season 5 and it feels like there’s potential growth of some kind of relationship there. I’m not sure if that’s a friendship or potentially something more.”

The creators are keeping Eliza and Blake’s relationship a little mysterious. They are not spelling out if it’s just friendship or if there is romance brewing. But you can tell things are changing in Miss Scarlet Season 6. There is more emotion, more complexity, and bigger stakes coming their way.

Here is what stands out about how their relationship is evolving:

When the show says “working together may be a tricky prospect,” it is clear that Eliza and Blake will team up on more cases. But it won’t be smooth sailing. They clash over how they work, trust doesn’t come easily, and their past keeps getting in the way.

Blake starts pretty wary: he doesn’t trust private detectives, and he doesn’t hide it. But that gives the showroom to build real respect between them. By Season 5, you see that shift. Eliza is not just some outsider begging to help; she has proven herself, and now she stands as an equal partner.

The Season 5 finale shows a new side of Eliza. She is open to more, emotionally. The showrunners hint that we will see her personal life get more attention in Miss Scarlet Season 6. Even Blake’s actor has teased that romance is on the table.

Their relationship isn’t just about them; it’s also a symbol. Eliza is still breaking ground as a woman in a world run by men, and Blake holds his place at Scotland Yard in Miss Scarlet Season 6. Their dynamic plays with the push and pull between needing each other and standing alone. Fans notice this too: some worry that if things turn romantic, it might water down Eliza’s independence and drive.
