Doctor Who and the Poison Sky

Rose pops up from nowhere. Surprising Torchwood reference. Genius goes mad and shouty. The Doctor casually insults humans. Does it get any better?
What did Rose mouth anyway? “Doctor”? Is the other universe being invaded and their Torchwood can’t handle it? I hope so. Then I’ll be right for once!
Anyway, an improvement on last week’s. The tab above leads to my episode list, with ratings.
