Graff carried her through the forest. As he did he started to explain the ceremony to her. There was a lot to remember, but luckily she didn't need to remember much and he could lead her through those parts. He had spent a lot of time memorising the ceremony when he had heard about it. It was important to do it properly. If not, it might go wrong. When they got to the site he ran her through it again, showing her what they would do.
