"When we thought about it, we thought a lot about the final Fugitive episode which took place at an abandoned amusement park. I just wanted big real estate for the last acts of the episode…He's taken a young girl hostage and Olivia knows there's only one way to get this girl freed and that's what he wants her to know," Leight told E! News.

But will this interaction provide closure for Benson?

"I think it's going to provide some closure, but exacerbate and reopen—it's not great for your PTSD to have the guy who took you hostage escape from prison and try and lure you into a one-on-one confrontation," Leight said. "It's going to in some ways reopen some of those wounds and he knows exactly what he wants and what he's doing. "

In the time since Benson last faced off with Lewis in court, Cragen (Dann Florek) retired as captain and Benson became leader of the squad, Amaro (Danny Pino) shot an unarmed 14-year-old kid and Rollins (Kelli Giddish) is in a bad way with a gambling disaster. And then there are the Benson and Cassidy (Dean Winters) relationship struggles.
