Young Time Lord and seraphim writing together.

Scott:273 year old seraphim with scruffy white wings. He met The Professor when he was going through American junior high, hunting a rogue demon. They weakened the demon using Scott's 'angelic' powers.

The Professor: I'm writing this profile. I'm 392 years old. I found our TARDIS a very long time ago, on a street corner in London. I met Scott several years ago. he told me he was a servant of 'God'. We were looking for an member of the species Alitrawe. We cornered the alien in an American junior high after several semesters of playing at school. I asked him to travel with me. We enjoy running, flying the TARDIS, and arguing over whether 'God" exists.
