Welcome Back to Dumbledore's Army!

Neville Longbottom is bringing Harry James Potter, Hermionie Jean Granger, and Ronald Bilius Weasley back to Dumbledore's Army in Harry Potter and the Deathly Hallows (Part 2.) There is a hole in the wall that actually opens and closes to reveal the room of requirement, where the D.A. is camped out. I used A-frames, backwards building, hinge bricks, window shields, and a 6 x 8 brick with holes to make the tunnel that goes from the Room of Requirement to the portrait of Ariana Dumbledore in the Hog's Head Pub owned by Aberforth Dumbledore in Hogsmeade.
