Luke is generally a compassionate and kind-hearted man, but is capable of detachment and distrust to the people whom he believes to be a threat to himself and the group. Though capable of keeping a cool head in the face of latent panic, when the situation becomes potentially disastrous, Luke is often seen to panic and, possibly subconsciously, defer the decision-making to a more sure-spoken person. Despite this, he is caring and protective when it comes to his friends.
