Peter Sam and the Refreshment Lady is the seventh episode ever made in Season 4.
Peter Sam is now single-handedly running the Skarloey Railway and is happy with his new position, but when he is late one day, Henry threatens to leave without Peter Sam's passengers next time. Peter Sam is worried and hurries as much as he can, but becomes impatient when he has to wait at the lake for an hour and leaves without a very important passenger: the Refreshment Lady. Peter Sam gives the Refreshment Lady an explanation, but the Refreshment Lady informs him that Henry was joking. Peter Sam is furious, but Henry had disappeared.
- In several scenes, Henry is wearing one of Gordon's face masks.
