Invasion! (Arrow)

"We can't stay here, Speedy, no matter how much we want to. We can't. Why not? What is waiting for us, wherever we are right now? Nothing. Nothing but pain and s-suffering. Thea, we have responsibilities. We have people who count on us. There's Flash and--and Supergirl and--and people with actual powers now. Whatever needs to be done, they can handle it. We--we finally have a chance to be happy. I mean, why--why can't you just for a second accept that maybe this is your reward for all of the sacrifices you have made? I didn't make those sacrifices for a reward, Thea. I did what I did because I thought it was right... And seeing all this, it has just-- it has shown me that there is still so much more to do, so please, I'm begging you to come with me because I cannot do it alone. But... I can't lose them again. I can't lose my family."
