❝ It’s so nice to know that in some alternate universe, spliced with a little bit of human DNA (from the marvellous Donna Noble, if you remember – I expect all their children have bright-red hair), this Doctor, alone of all the transfigurations, was allowed to fall in love with Rose, settle down and live happily ever after. The Doctor so rarely gets a chance to be happy, but this one did.
