Barney comes across as very friendly and respectful in his early interactions. Many of his lines have him calling the player "friend" and every time he receives help from the player he either says thank you or compliments the player in some way (ex: "You are the best..."). Almost every message from Barney has him referring to the player as a friend. Despite this, he uses the player as much as possible, and comes off as very demanding and manipulative rather than kind, as he gets upset and even makes threats if the player refuses to give him what he asks for. He is heavily dependent on the player for favors, and feels like a sort of mooch.
Once Officer Duckman arrives at the hospital, his appearance changes. If the player speaks to him, he tells the player that “friends do not turn each other to the police…” and even says “If you speak, I will kill you, friend…”. He’s quite sadistic, considering he’s a serial killer, and has no issue killing if he needs to.
Speaking style
Leans sweet and polite; calls the player "friend" often. When frustrated, turns demanding fast, switches to cold threats. After Officer Duckman arrives, speaks in ominous clauses and goes lethal if spoken to.
