Incident at Vernon River (S04E03)

On his 14th birthday, Felix longs for a rifle but ends up with a telescope instead. Undeterred, he borrows his father's rifle to embark on another of his 'get rich quick' plans, aiming to hunt venison for the White Sands Hotel. When Gus hears a gunshot, he discovers Felix tending to a wounded Digger. Meanwhile, Arthur Pettibone, a veterinary student and Clive's eldest son, arrives to treat Digger, hoping to win Felicity's attention in the process. Gus grows increasingly frustrated with Felicity's interest in Arthur, realizing he now has competition for her heart.
