Hal had never intended on moving to Gotham, but life, lemons, and the hatred of all things yellow left him with little choice. This was Batman's city and that was the exact reason why it made him uncomfortable. Not because he was scare of the big, bad Bat, but because, somehow, everyone else was. He would never understand this place, yet he could understand how the hoards of criminal masterminds never failed to strike time and time again; Batman was incapable of simple tasks.
Before he had left, Hal had requested that Batman keep Dinah safe. It was the one thing that he had ever asked of the man and yet he returned to find out that Batman failed spectacularly. Instead of keeping his friend safe, he found her in the arms of Bruce More-Handsome-Than-Smart Wayne. That was the opposite of safe. It was time to talk.
It came as no surprise that he found Batman taking out the trash. If Hal had arrived just a few moments earlier he would have lent a hand just to pepper in some annoyance for the night. But he could still exact some revenge. "Fair enough," Hal said and extended his ring hand. Batman would soon find himself encased in a green, glowing orb and far off the ground. Hal didn't take them far, just far enough to be annoying. He dropped Batman on the flat ground of rooftop a few blocks from thee crime scene before his own feet touched the ground. "If this isn't far enough the next stop is space."
