It’s Freya’s first day off in weeks and Sam wants to get her out and away from a computer, so she and Gus (Andrew Ryan) offer to take her on venomous spider hunt. Freya is excited to see what Sam and Gus do when they are not working in the Clinic. When Gus slips and falls - into a Gympie Stinger Bush - her trip into the rainforest is cut short. Treating a tortured Gus at the clinic means a long, painful procedure to remove each of thousands of toxic needle-like hairs. Sonny offers to take Freya snorkeling and she accepts - anything to avoid hearing Gus howling as Livvy uses hot wax to strip off the hairs. Freya has her first close up look at the wondrous reef. It’s when Sonny loses consciousness and nearly drowns that Freya experiences a real test in emergency medicine.
