Grian is an alien, he fell into the world by accident when he fell asleep whilst driving his space craft, it was Joe who'd found him, and instantly brought him to X, all the hermits had been wary of the strange creature, who didn't seem to speak their language. It was doc who offered to take care of the 'creature' knowing full well how it feels to be a 'threat' to people he cared about. He taught grian English, as well as many other human languages, impressed by the speed at which he learnt things, Grian told him he was escaping his own world, Where he was marked for execution. Doc comforted him and made sure everything he does is happy and good. He's never loved someone so much as this tiny loud alien.
Maybe Doc can relate to the whole “escaping his home world” thing.
