A conference of the galaxies greatest minds is convened to brainstorm about the Magog Worldship and what could be done to prevent disaster. Who better to put in charge of this meeting of the minds? Seamus Harper. No, we don't think that was a particularly smart idea either, but Dylan was called away on another matter so this is what we got. It's an episode of intrigue, name calling, lots of sass, and yes, brains: "Machinery of The Mind".
