First off, I do understand the episode was about a mental breakdown, grief and loss.
What I can't fully understand, is what David was trying to achieve with the shoe? It was obviously his own shoe and it served as a plot catalyst. But what i cant understand is why he would plant one outside knowing the other one was in the house somewhere.
David's main goal throughout the episode was to find the owner of the shoe. If he was trying to find the other shoe to go with the one he found I could understand it more. Like trying to reunite the shoe somehow made up for losing his twin boy.
We saw the picture of him in the shoes at the end.
I'm just a bit confused about the whole shoe thing and why he planted it. Sorry
Actually typing this out and reading it back now maybe things make more sense to me. Was David hoping to reunite his single shoe with someone else who had lost a shoe? When the guy from Norfolk picked up the shoe David was finally at peace until he discovered it was a setup and he lost the plot again.
How do others see it? cheers
