thought mcgonagall was saying "cockroach clusters" at the gargoyle and doing her thing with Albus.. Him being a supreme lelligimence and having those piercing blue eyes and saying "Minerva, I know what you want, witch."
But I find he wanted Gillert Grindlewald... Which raises questions about their legendary duel. I mean, how could he have won the elder wand? Maybe because they fancied one another and Grindlewald hesitated and Albus won the duel and wand.
Anyways, it makes sense in a weird sort of way. Maybe Dumbledore abandoned his fancy of Grindlewald after Ariana's death..
