The reality keepers

The reality keepers are the creators of Thomas’s spaceship “the Flying Scotsman“ They are never really shown, the only time was at the end of season 1 when Thomas had the reality illness form never cleaning the Scotsman. He had many hallucinations and in one of them this image was shown when he was shouting out other worldly words. Its not really known if this is what they really look like. The only real reality keeper was the door to door sale man from the first episode.
