Frank has been desperate to start up a whole new mythology for the island with stories featuring various characters he's modelled out of seaweed and goggly eyes, so Nadia's relief was positively palpable when Louie Stowell turned up, courtesy of a feathery Loki, with enough Norse tales to sate Frank's ravenous appetite, at least for a little while.
