Well he would know Bobby however I doubt she would like him much. Partly because there are very few people she does like, however mainly because something about him irks her (which isn't saying much either, she is easily irked). In any case she will probably make random threats of castration and maybe abduct any pets he happens to own.

Josef might also know of him, but Josef rarely talks much and Brandon isn't in his house or anything. Just let me know though if you have any ideas, I have a whole ton of other muses floating around as well.
