Journey, the North Coast:
This encapsulates the idea of a physical discovery overwhelming an individual. Gray lived in a "furnished room" for 12 months and was unable to explore the world, hence, when he journeys on the train and discovers the beauty of nature, he realises the importance of life.
Late Ferry:
Explores simple events that become extraordinary through a different perspective. Perspective and renewed perspectives tie into discovery well as they change and shape a persons identity. Identity is a feature of self-discovery.
Both Late Ferry and Journey, the North Coast have subtle discoveries but you can make connections
