I think it goes without saying that Prizrakov and Prince will butt heads whenever they're forced to be near each-other. This could be quite a bit of fun to write, though! I'm not quite sure how Rodeo and Prizrakov would react to each other; Prizrakov might get annoyed that he is refusing his help, and he IS a world-class physician. Politeness is key when dealing with him; he was originally quite upset that English doesn't have a second-person-singular to differentiate from the plural. He calls his wife 'thou,' at times, to make up for it. And any addition to his butterfly collection is greatly appreciated, however :)
