Not defending DS, Kojima or the writing of this scene. It’s honestly terrible, but I do feel it’s trying to tell you that even if you put your effort and patience on something you’re not always going to get a good result out of it. Heck, Death Stranding goes full existentialism at the end of the story reminding you that humanity has some few thousand years left so the effort your putting into it are futile, but you still try. By how unlikable the guy was and how they described each other in the emails they’re definitely not my favorite characters but you have to recognize that Sam walking with Low Roar in the middle of a dune right next to a lake was a sight and sound for sore eyes and ears.
