Maybe this would be 5 stars for me if I knew what Bridgerton was...? Alas, I'm habitually uncultured. What I do know is that this episode is great fun. Jonathan Groff was an unknown to me, but he is a revelation as Rogue, who immediately charmed me. I do hope that we'll get to see him again soon, as his blooming romance with the Doctor was pure delight for me.

As the story lives and dies on this relationship dynamic, the villains end up feeling curiously incidental. The Chuldur are... fine. They mostly look good, though it drove me crazy that their beaks weren't connected to their mouths in some way. For shame! (This is not a serious criticism.)

I thought Ruby's side plot was pretty good until her new friend ended up being a Chuldur. Nice twist, but a shame to lose what seemed like a potentially great character dynamic. The fake out where we're led to believe she died is classic RTD, though I'm not entirely sure why it's here.

Minor quibbles aside, I think this holds together as a solid to strong episode, and it may grow on me with time, especially after further appearances from Rogue. Please? Please?
