Scotty is 19 years old, during the apocalypse he wasn't allowed out of his cabin because of his father. Scotty is broken, he's confused, he's afraid of his overprotective father. He is first introduced in season 3 episode 11 when Javier and Eric are kidnapped by his father. His father got his mother killed at the start of the apocalypse and his father still keeps Scott's zombie mother in the garden tied up, because the father still thinks that she's still alive inside. The father kills people who come near the cabin and feeds them to the mother to make her keep going. The son knows she's dead but he never confronted his dad about it because he was afraid that the father would kill him in anger. In episode 11 he finally confronts his dad about it. Throughout the series, we will see him go from broken boy to a free man. Oh and he sounds like Jesse Pinkman from Breaking Bad.
