This is part of a series of reviews of Doctor Who in chronological timeline order.

Previous Story: Children of the Revolution

Easily the best so far. Instead of trying to pack a whole story into 30 minutes it's essentially a character piece for the Doctor and Peri instead. 6 and Peri's dynamic is at it's best here. It's also very atmospheric, we're on a completely snowed over planet that's slowly melting and the soundscape for that is phenomenal. We also finally meet the quin Ervis whose been referenced over and over throughout the set and honestly I'm a bit disappointed. I thought they'd do something a bit more interesting with the whole "everybody hates him" and have him actually be the only nice, well-rounded quin but they went with the boring option. Good story though, overall.
