He probably has 18+ Intelligence - I doubt he even needs to find secret letters in V's spellbook to put two and two together.

If it was me, I'd probably try to talk things through with my young apprentice. All the while thinking "I bet Yoda never had this problem!" And I'd strongly consider sending her to another teacher.

Of course, if V is really in love with Aandy, such a thing could lead to her trying to convince him to love her. I hope Aandy casts Hold Portal before he goes to bed...
