Doctor Who: 10 Most Poetic Moments

10. Finding Love (Human Nature/The Family Of Blood)

Hiding from the Family of Blood, who want to harvest his life force, the Doctor transforms himself into a human and places all of memories into a fob watch for safe keeping until the Family have died out.

The Doctor's logic is sound, especially as he has Martha on standby, posing as a maid to ensure that he will know when it's time to take his memories back. Busying himself with teaching at a boy's school in 1913, The Doctor (or John Smith, as he believes his name is), encounters an unexpected hiccup: love.

Joan Redfern, the school's nurse, quickly becomes a romantic interest for John Smith, and she takes a marked interest in his dreams of his life as a Time Lord - making it feel as though we're being prepared for Joan to travel alongside the Doctor as his new companion.

Upon realising that John Smith is the Doctor, the Family of Blood take Martha and Joan hostage, and force him to choose between giving himself over to them or watching the women die.

Just before the Doctor resumes his Time Lord mantle, he shares a vision with Joan of what their life could have been had he remained human. Seeing the Doctor in this light was a first for many, and although the build up to the moment they share was relatively short, it was still incredibly bittersweet.
