Luke is a relaxed officer, he may seem chill but in reality he is one of the most skilled cops in the city, he took on two crime cases by himself and graduated top of his class, he is good at descalating situations but wont hesitate to threaten someone if it meant the safety of someone innocent. 
Luke is a tall but slightly skinny figure, hes cool but has a small temper, he can control it, but growing with 4 siblings hasnt helped him but to grow more over protective of the victim in his cases
