Gwen told me her idea to send Haley off and I was excited about it.
She said she and the writers went through all the options and weighing what would be the best story.
Upon reflection, she admits that much like her character, she eventually found herself at a crossroads.

Yeah, that was essentially it.
I love this group of people, everybody from cast and crew, producers, everybody.
This was a really hard decision to make.
Ive been on the show for 7 1/2 years.
It was very bittersweet and emotional.
No, I mean, not that I know, she said with a laugh.
Olinsky died in the Season 5 finale after he was knifed to death in prison by an inmate.
Its been a long time coming, Sigan says of Olinskys return.
Jason Beghe gets all the credit for this one.
Hes had this idea for a while, really wanting to bring Elias back in some way.
It was really special.
Its new and different than what shes done before.
Of course, I love Halstead and that would have been cool too, so dont get me wrong.
I hope they like that she gets a happy ending for herself.
She gets to find herself and make this decision of whats best for her.
Spiridakos is walking away on her terms with happiness in her heart.
And as any OneChicago fan knows, is that most of our favorites never stay gone too long.
I would love to reappear, that would be amazing.
I love this whole group of people.
I think as far as a parting message, I would just say thank you to the fans.
Thank you to the Chi-hards for welcoming me into this lovely group of people.
Im grateful to all of you, she concluded.
