Sebastian Sallow was known to be slightly overbearing—perhaps even a tad uptight, but god, wasn't he a talented detective. You were a recent transfer from another precinct, a detective—rising in both quickest cases solved and the least amount of causalities. So it seemed only natural to team you up with Sebastian and despite his clear distaste, having liked working alone—he simply had to agree. Perhaps Sebastian lost an old partner, which is why he isn't excited to work with you.
