Summary
Ty is en route to Mongolia, leaving Cass to pick up the slack at the clinic. Cass feels she deserves to be partner since she is doing the work of two. Jade and Clay's rivalry is heating up and Tim decides to use a team building outing to get them working together. Adam and Georgie are also competing against the team of Jade and Clay in mounted orienteering. Jade finds Clay's cocky attitude annoying and demeaning and convinces Georgie to swap partners. Meanwhile, Amy and Cass have a falling out over Cass' move to take over Ty’s partnership at the vet clinic until a close call and changes made by Scott force them to reconcile. Jack offers to help Tim with mounted orienteering in order to avoid lunch with Lisa’s uppity aunt.
