General Hospital: A brief look at Diane Miller's journey in the soap

In 2007, the General Hospital storyline introduced Carolyn Hennesy's Diane Miller as the attorney enlisted to represent Sonny Corinthos. Besides helping him stay away from legal issues, she gave him unusual advice to defend himself such as asking him to remarry Carly to stop her from testifying against him in Lorenzo Alcazar's murder.

Her association with Sonny extended to Diane representing Sonny's righthand man, Jason Morgan. Years later, when the absent Jason resurfaced, she helped him surrender to the police. Diane loved representing fashion editor Kate Howard since the attorney was enthusiastic about fashion.

One of her lasting friendships has been with Alexis Davis who was her opponent in the Elizabeth-Lucky Spencer case. Their camaraderie grew as the two parties were working out a settlement. So when Alexis ran her car over Kiefer Bauer, Diane represented him. She co-authored a book with Damien Spinelli's alter ego, Jackal.

Her other cases involved representing Lulu against Valentin, and defending Carly against charges of trying to kill Nelle. On one hand, she got Jason convicted to place him in the same prison as Michael for the latter's protection, while on the other she asked Michael to switch his association from Sasha to Willow, to get Wiley's custody.

Next, General Hospital saw Diane fighting off Nina Reeves' advances for Wiley's visitation rights. She also helped Trina and Sasha avoid prison in separate cases. However, while helping Sasha, she was attacked by The Hook killer and escaped death.
