Signal

Communication in Middle Ages
At one point in Episode 8, Argaï, Barnaby and Oscar go to the Middle Ages with a little invention of Hugsley, so they can still communicate. After some little tests, this seems to work. Only later, when they enter a Pyramid, the communication fails. Both Barnaby and Hugsley mention that they are in the Pyramid and the walls are too thick. Rather strange, as they can directly communicate between the future and the Middle Ages... This would mean that they have satellites in the Middle Ages and the connection fails because the Pyramid blocks the satellite signal! Ah well, continue the story.
