Isaac had to get out of there quickly. He knew he had a limited opportunity and he took it, He managed to run out quickly but quietly, careful to not draw his captor's attention and once he was outside, he could at least relax a little.
He put what were now his boots on and started to walk, cutting through lawns but at a slower, more deliberate pace. Once he was beside an old house quite similar to the one he had just ran out of, he could calm down some. He at least now knew where he was.
As he walked, he knew how he had to look. His head on a body like this had to be a very strange sight, but there was nothing he could do about that. He had no illusions about the likelihood of getting his old body back, so he might as well start to get used to it. As for that house and that strange man, he had no plan for that. One thing at a time.
