‘Doctor Who’ Episode 6 Recap: A Charming Rogue

Season 1, Episode 6: ‘Rogue’

For decades, cosplay has been a huge part of the “Doctor Who” fandom, with hardcore viewers rocking up to conventions or gathering to watch the show decked out in Tom Baker’s striped scarf or David Tennant’s slim suit.

“Rogue,” this season’s sixth episode, is a meta meditation on cosplay — a portmanteau of costume play — and obsessive TV fandom, as the Doctor (Ncuti Gatwa) and Ruby (Millie Gibson) travel to Regency-era England and face off against a shape-shifting alien species who want to “dress up and play at ‘Bridgerton.’”

Initially, the repeated explicit references to Netflix’s blockbuster show — as well as the enemies-to-lovers plot, the copious wisteria and the orchestral covers of pop songs — feel unnecessary. But it soon becomes clear that “Doctor Who” is engaging in cultural cosplay of its own.

The year is 1813, and the Doctor and Ruby set about immersing themselves in the party of the season. Ruby quickly gains the attention of the night’s host, the proud Duchess of Pemberton (Indira Varma, “Game of Thrones”) and shocks the rude Lord Barton (Paul Forman) with her 21st-century slang and feminist principles.

More than just an old-fashioned misogynist, Lord Barton is secretly a Chuldur, a member of a species of intergalactic social climbers who rise up the ranks by taking over the bodies of the powerful and interesting. First, they go for Lord Barton; later, the duchess becomes their next victim.

The Doctor has never met a Chuldur before — not that he knows of, anyway — but he can tell something’s up. Scanning the room, his eyes fall upon a brooding, aloof nobleman called Rogue (Jonathan Groff, a notable King George in “Hamilton”) and the orchestra plays Billie Eilish’s “Bad Guy” to really hammer the point home.
