Eotain and Shurdlu/Mad

Identity
Eotain and Shurdlu may (or may not) be indistinguishable, but they are not in any case identical; they have separate memories and reactions. One of them is amused that they at first mistook Agatha for a mere actor, the other is dismayed. One finds Dingbot Prime delightful, the other is disgusted. Whether the it is the same one with the more carefree attitude and which has which name has not been analyzed.
