Raviv

Raviv Artemis Osgood Osgood, otherwise known as Ravivaboysbarrowosgoodartemisosgood, is the only writer ever. They have incredibly complex headcanons which they are too lazy to make into actual fanfic, and everything they say is valid. All hail O/sgood, ace lesbian Osgood, and Jewish Osgood.
Raviv is jewish and extremely lesbian. They may or may not be a Zygon.
do not talk to them about Osgood's death that definitely didn't happen. she's fine. she's alive and well.
One day Raviv will become a writer for Doccy Who as The Prophecy foretold. and then you will all be sorry. 
Raviv has no sense of identity outside of Osgood. This is because they are Osgood on all levels except physical. Raviv will ascend to full Osgood form when they have fulfilled The Prophecy and made Jewish Osgood canon as the one true doccy who writer.
After they have ascended to Osgood form, Raviv's clone will be summoned.
