Rourke is very sarcastic, creative, impulsive, and resourceful. He isn't very social, as he focuses on training as a soldier and earning merit. However, he is shown to be good at persuading other people to his side. For as long as he could remember, he had been trained as a soldier by the Core from a very young age. For him, 'common sense' was just learning how to use a gun or control his breathing. As a result, he lacked knowledge of being anyone but a soldier, and this made him blindly loyal.
