Gabe is a lovable nerd who is in love with Patricia Wan. He's a teacher at the local high school and is oblivious to the conflict between his daughter and Patricia.
Gabe O'Mackey lives in Riverblossom Hills with his daughter Jules. He's in love with Patricia Wan whom his daughter disapproves of. He is in the Education Career Track as a High School Teacher. His ex-wife, Alexandra O'Mackey, divorced him when Jules was a child in order to become a Dread Pirate. He has one brother, Jason Greenman.
When first played, he is 25 days away from becoming an elder. This makes him far too young to have a teenage daughter, so it is probable that he had access to the Elixir of Life.
Oddly, all the memories of his life have the green positive background, including breaking up with his wife and his parents' deaths. Another oddity is Gabe considers his sister-in-law Rose family and vice-versa.
