I am wondering how Theo's family story intertwines with the Heterodyne Boys and/or the other Mongfishes. I suspect we're not really going to get into that, but I would like to know just how long Theo's been under Klaus' care, and I'd love to know who (if anyone) his parents associated with. He does seem to have a special exemption from Klaus' "Mongfish=EVIL" thinking. Uncharitably, maybe because he isn't a girl? Or maybe just because he's been raised on Castle Wulfenbach, but being raised away from family influences doesn't seem to come into Klaus' thinking about Agatha very often (once, if I remember correctly).
