Augustine is a teenager of average height with fair skin, brown eyes, and thick brown eyebrows. He has short and spiky dark brown hair. Augustine wears a white t-shirt under an orange, white, and blue striped jacket. He also wears a blue and orange ushanka and is seen carrying a blue bag. At the beginning of the game, Augustine struggles with self-doubt regarding his friendship with Vinnie, particularly due to the long gap in their relationship following an incident where Vinnie broke his leg. As a child, Augustine exuded a bright and cheerful personality, and was noted for being forthright in expressing his opinions about people. Notably, he insulted Vinnie during their first meeting as children, expressing a preference for forming friendships on his own terms rather than being pressured by his parents. As Augustine matures, a noticeable shift occurs, manifesting in a more bitter attitude towards Vinnie. He approaches situations with a heightened seriousness, is prone to violent outbursts of shouting, and has a distinct sense of reality distinct from Vinnie's. Augustine displays moments of coldness, is occasionally paranoid about Vinnie's opinion of him, and experiences vivid hallucinations, particularly imagining Vinnie as hostile - a possible manifestation of his underlying hostility. Overall, Augustine appears as the darker of the two, driven by self-doubt and a relentless search for answers.
