Mr. Personality
The first time we meet Harrison, he's meeting Quinn Perkins for a drink. But it's not a date, it's a job offer. Since then he's kind of taken her under his wing and helps show her the ropes at the firm. From there, he serves as Olivia's point-man when it comes to dealing with people who are hard to deal with. He's dealt with an infamous madam, a South American dictator and local District Attorney David Rosen. His keen ear and attention to detail also helped clear the name of an airline pilot wrongfully accused of causing a crash.
