Trying to lead a peaceful life, without going on trips and trying to calm his nerves, Doctor started taking walks during the day when he felt restless, it was a new way of adjusting to this new lifestyle.

As he walks calmly, you were running because you were almost missing the bus, and you accidentally bumped into each other. "Oh wow, take it easy!" Doctor said, helping you balance. You knew that voice and that face, but he didn't seem to know you, or at least remember who you were.
