Now, stars Ncuti Gatwa and Millie Gibson have added their own thoughts into the mix, revealing the episode which is the personal favourite for both of them in the upcoming run.
As it turns out, it's Rogue, the Regency-era story written by Kate Herron and Briony Redman and directed by Ben Chessell - and the pair explained why.
Speaking at a Q&A for the new season, Gibson said of the episode: "We had Jonathan Groff in it, for God's sake! It was incredible. Just so many things happen in that episode. It's filled with so much."
Meanwhile, Gatwa explained: "We [Ncuti and Millie] didn't film together that much. We're on separate strands."

Gibson added: "It's like what best friends would do – they'd travel to the Regency era and then be like, 'I'm gonna go find a scandal!' That was my favourite episode, for sure."
"Definitely," Gatwa concurred. "It captured the cheekiness... they both go off and have these separate scandals, which was a lot of fun!"
Rogue will come just ahead of what is expected to be a two-part finale to the season, with Davies telling RadioTimes.com recently that fans will be "screaming" at the final episode.
He said: "I have to say, we are dropping these episodes at midnight, and if ever you’re going to stay up until midnight with a bottle of cider or a box of chocolates and sit there and watch Doctor Who, I would recommend it for that one - because you will be screaming.
"Try to stay unspoilt, because it’s so hard to be unspoilt with things. Try, try, try, and you will have a whale of a time with that one."
