Marmalade Magic and The Aftershock.

Mark has been making the most amazing marmalade, the method for which was taught him in a dream by an underwater terrapin-helper. Mark has always been able to remember any dreams he has, asleep or awake, and also to learn from them; Mark is a lot more evolved than most people. The marmalade is made almost entirely of the Underwater Oranges of Doom, but the terrapin method neutralises the doom, thank goodness. He has never let on what exactly he does but Ced rather cynically suggested it might be down to nothing more than the old terrapin magic, which generally does one ot two nice things in return for a lot of grief and we don't want to encourage especially after the last time. Even if the marmalade is as good as this it really isn't worth that sort of massively outbalancing downturn with, potentially, years of aftershock.
