Upon seeing the girl clutching her head, Rachael wandered over and took a seat next to her, reaching over to put a hand on her shoulder.  "Migraines, huh?"  Without waiting for a response, she used her other hand to pull out a packet of Excedrine, placing it on the desk before Luna.  "I used to get those while I was growing up."  Hers were part of being a doppleganger, when her growing pains kicked in and parts of her head didn't quite want to stay in the right place, but she left that part out.
