Watching the series, one of the first things I thought about Emma's faerie-induced greying was that she was gaining something of a Bride of Frankenstein look (yes, I know, movies not book, but still). And, well, travelling Europe with Arabella, Flora and the poetic set, there's the original author herself. So. Mary Shelley finding a muse and a lover in this wild, resurrected woman who takes no shit from anybody? Maybe throw in Emma developing something of a talent for weather (storm) magic along the way?
