Oliver heard that voice and it made him look up once for the first time. Once he saw that it was indeed Laurel he couldn't help the smile that appeared on his face for just a few seconds. She always brought that out of him. But the smile was only there for a second before he pushed it back down once again; he knew he had no chance of making things right with her. He couldn't be that close to her again and not be able to tell her the truth.
"Hello Laurel" he said with a friendly nod. He knew if he kept talking he might not be able to keep his cool if he got too much closer to her, so he leaned back a little.
