Zagreus Is The Stardust's Shame, The Beast That He's Been Keeping

A nursery rhyme from the Big Finish Doctor Who audio dramas. The amusing idea came to me about incorporating/mentioning this rhyme in one of the future chapters of season five. One verse recited by Stardust, the next by Sombra, then Starswirl and so on. Plus, is it just me, or does "Zagreus" sound like a fitting name for a villain...?
