It is relevant. At least it would be if I could decide if Aerith should be good student / bad student. Because goodness knows that math beyond the basic algebra level would probably confuse and then bore her. XD

Also A-OK with Mercury / Ami being the "trusted friend". Although which form she's in will make a difference, Aerith does trust "Mercury" from their first dream. ...Actually it'd be kind of funny if the trust went both ways and Aerith found out Ami IS Mercury, but ... not sure if that would even work in the dream's context.
