The first time the fans see Oliver Queen interact with John Diggle, Felicity Smoak, Tommy Merlyn, Laurel Lance, and Thea Queen, On Arrow Season 1 Episode 1 and Arrow Season 1 Episode 3
Lance: I may not always agree with your methods, but I can't argue with your results. You saved my daughter. Again. Arrow: She needed my help. Lance: She wasn't the only one. Thanks.
Are you done? Oliver; Yeah, I'm done. I'm done taking the blame and I'm done caring. Why don't you go have a drink. Get wasted. Go to Verdant. I'll pay for it. I have loved you for half of my life but I'm done running after you.
