Osman "Oz" Bey is Toby Logan's best friend, former EMS partner, and new neighbour. Oz is a talker, a wit, and a joker.

Osman, or "Oz" as he prefers to be addressed as. He is a very carefree guy and tends to make a lot of jokes. He is a ladies man of sorts and likes to chase them. Although, in Some Kinda Love, Oz admits that he doesn't like to be chased and wants a bit of a challenge with a lady. Oz is loyal to his friends and once he learns of Toby's secret, he protects it and Toby.

Oz seems to like Jade's music, but doesn't admit it to Toby


Spoilers Ahead!!!

Oz meets Toby at the dinner before work. They talk about Toby's on/off girlfriend Olivia and about their job as paramedics. Oz is driving with Toby talking about work, when Toby begins to get an intense headache. Worried for Toby, Oz pulls over and soon discovers there is a car flipped over on the road. Oz and Toby rush to assist the woman, and Oz freezes. At the hospital Oz applies for overtime for having Anna, but Ryder comes in and deinies it. Later on Oz wants to talk about what happened in the car and Toby tells Oz that he was assessing the situation. When going to get Anna, Oz decides to go get coffee.

Oz and Toby are running one big chess match game using Toby's abilities. On the job one day, Oz and Toby make a stop and while Toby goes into the bank, Oz gets a hot dog. When Toby takes too long, Oz investigates and eventually figures out there is a bank robbery going on. Oz soon calls the police and then Michelle for assistance.

In season four, Oz is moving up in the world, taking on the role of Director of Emergency Services at St Luke’s Hospital. Oz still finds himself carefully navigating his way through a kind-of-serious relationship with nurse Sandy, including meeting her dad and having her move in temporarily. Thankfully he’s still able to knock on neighbour Toby’s door for a beer or advice – or both.
