I keep thinking about all of the journey imagery that was used in the last few seasons and the “River shall end at its source.”
We’ve arrived at the source. Mary’s alive and Sam and Dean are struggling with what that means for them. So here we have Dean fumbling over road blocks and dropping and breaking ships. They’re played lightheartedly, but it seems like it’s a way of reinforcing how much he is struggling along this journey.
