Hey Mister...
Albus noticed that Grindelwald was right in front of him addressing his followers, but he has his back to the entrance. 'Foolish man,' thought Albus, before realising that the wards were probably in place again now. Albus then noticed the woman beside Grindelwald. She still had her glamour on, but Albus could see bits of her returning, like the fact that she wasn't wholly cooperating with Grindelwald now.
Albus decided that it was time to reveal himself and get it over with for good. He quickly stepped back outside and sent an owl to Minerva's friends Alastor Moody, now an auror, and Poppy Pomfrey, the healer at Hogwarts. They had gotten together just before he and Minerva, and were spending summer together on the south coast of Britain, helping with the war. Albus then remembered the wards, and cast a diagnostic spell. He knew Grindelwald from old, and could still remember some of their old secret codes they had used to cast and uncast various protection spells. Albus smiled. Grindelwald, sure he wouldn't be caught, had only cast a light protection spell that could easily be penetrated by someone who hadn't cast it. Albus did just that, and set up his own, much stronger, protection spell, which would allow the aurors in but wouldn't let the dark wizards out. Albus smiled, as Alastor and Poppy appeared, although nobody heard them arrive, as Albus had also cast a silencing charm upon the pier. Alastor smiled at him
"good work, mate." he growled. "the reinforcements are on their way." soon, a minature army of aurors were beside Albus, aswell as a few more healers. Albus addressed them all quickly.
"I have just checked. He is the same as before. He looks as if his back will be to us for a while. I shall go in and reveal myself, and he will think I am alone. As soon as you hear the spells, burst in and duel. But let me have him." he said strongly, fire burning in his eyes "for he has Minerva."
With that, Albus took his glamour off and turned invisible, before walking in and stepping behind Grindelwald.
Minerva, meanwhile, was sat, invisibly bound to a chair. She had noticed the man peep in around a quarter of an hour before, while others hadn't, and he seemed to calm her. He had then left, leaving her feeling calm, though she felt her memory coming back clearer and clearer.
As he suddenly appeared behind Grindelwald, she recognised him, and as he tapped Grindelwald on the shoulder, they both said the same thing at the same time - her to him and him to Grindelwald.
"hey mister."
