  • There was no linear storyline in season 1 with the exception of the 2-part season finale. The big deal, (Returning to the past doesn't resurrect humans) which was only explained in Teddygozilla and the final cliffhanger Code: Earth/False Start; but all other episodes could be seen in any order, or even not seen, while you can understand the whole story. That's why we don't see Theo in another season 1 episode than Claustrophobia, and Taelia is fully forgotten after The Girl of the Dreams. Interview with writer team of french forum revealed that it was a channel's exigence: they wanted kids to understand the story even if they miss some episodes or even if the channel released them in the wrong order!
