Review of Thin Ice
Warning: This review contains episode-specific spoilers and wild speculation about future episodes.
While Bill thinks she may be “low-key in love with [the TARDIS]” (which I thought was both a beautifully subtle nod to Bill’s sexual orientation and a lovely statement of sentiment), I’m definitely low-key in love with writer Sarah Dollard’s work.
Dollard, who penned last series’s Face the Raven, hit another one out of the park with Thin Ice, keeping Series Ten on solid footing. Bill is fast becoming my favorite post-Hiatus Companion, and the developments in her relationship with the Doctor under Dollard’s guidance are my favorite yet.
Following the Series One formula of modern-day introduction followed by a future adventure and then a past one, the Doctor (or, more accurately, the TARDIS) takes Bill to Regency-era London. I knew I’d love this episode the instant I saw Bill’s initial reaction to the time: reminding the Doctor that as a person with melanin-rich skin, she’s likely to have a different experience out there than he is. Better yet, Twelve actually considers her words before acknowledging the (general) danger and sending her off to choose a frock (in stark contrast to Ten’s complete dismissal of Martha’s similar anxiety at the beginning of The Shakespeare Code).
Throughout the episode, the chemistry between these two continued to fill me with joy. (I’m so crushed at the thought that we’ll have no more of Capaldi after this series, and likely no more of Mackie, either—which is nigh criminal, as she’s so bloody brilliant.) The Doctor yanks Bill’s chain at least twice about her interaction with time travel—the imaginary disappearance of “Pete” and seeing the lights under the ice—and proves himself both particularly admirable and particularly problematic in her eyes.
