37 - 42 Proof (S3, Ep7)

We watch "42" (Series 3, Episode 7) where the Tardis team discovers that life exists in some star whilst traipsing about the universe. After materializing on a distressed spaceship, the Doctor catches sun poisoning, Not-Rose gets harangued by her mum over the phone and everything still manages to work out in the end. See what we did there? The answer to that ultimate question will be released on episode six by nine.
