Episode 1.8, Ain't A Real Dog (Where Kat Was Impressed by the Voices, For Once)
Claire gives the longest, rambliest recap, but Kat likes it anyway.
The tables have been turned, and Hermione turns nurse to a splinched Sirius. The now-trio (since Ron is a whiny wizard and ditched) are down to one wand.
Ron gets over his issues and returns just in time to help destroy the locket. Then, just like the books, the Snatchers make their appearance. Claire pulls out all of the stops to do voices for Greyback and assorted Snatchers, as well as the incomparable Bellatrix. Kat is impressed. For once.
