Er...the symbol Lyta wears isn't "an interconnected IU that looks
an awful lot like the greek 'psi,'" ...it *IS* the Greek letter Psi, as

(Funnily enough, while in college getting my first degree in Clinical
Psychology, I belonged to Psi Chi, the national honor society in
psychology. Small world.)
