"It is not your problem to bear alone!" Oliver shot back. "You have family and friends who are there to help you deal with those problems. Who want to help you, not be shut out!" If she wanted a fight, then she was going to get one, for all that Oliver had said he would just walk away. There was no walking away here. Not when they were trapped here.
"And yes, I did push you. Because she's your sister, Laurel. Because I know what it's like to come home after five years and find my family more broken than I left them. I know what it's like to just want to be close to people again, but to always have that disconnect. To know that you're a different person, but to still be defined by past actions. But fine. I'm glad that you're getting your life together. I'm even glad you're doing it without me." He was just glad she wasn't going to completely go to pieces.
