It was an average night out for Batman. He had stopped several crimes, but they were all minor. There had been no activity from the villains of Arkham or Blackgate. It is always better when he doesn't have to deal with them, so he wasn't complaining.
As he was going from building to building, he heard yelling below him. Stopping, he looked down into the alley and saw a man and woman arguing. He was going to let it go as a domestic dispute, until the man roughly grabbed the woman. Thinking it was a mugging or worse, he decided to jump in and stop it.
Gliding down, he landed right next to the pair. Being closer now, he got a better look at them. Like most of Gotham, they were both very fat individuals. The man had brown hair and eyes and stood about 6'6", a few inches taller than Batman. The woman had red hair and green eyes, and was about 6'0".
"Let go of her now," Batman said, "and I might let you off easy."
The man gave Batman an annoyed look and continued holding onto the woman.
"Fuck off Batman, this ain't got nothing to do with you," he said.
With that said, Batman grabbed the man's arm and pulled him away from the woman. Angry at this, the man pulled his arm away roughly. He attempted to punch Batman, but his fist was caught. Batman kicked the man and managed to push him back against the alley wall. He grabbed the man by the collar of his shirt, ready to knock him out.
Suddenly, he felt a sharp pain in his neck. Reaching up, he pulled a needle out of his neck. He turned around and saw the woman, with a satisfied look on her face. He wasn't able to register much however, because he was promptly turned around by the man. With a similar smile as the woman, he drew back and punched Batman in the face, sending him to the ground.
He was definitely drugged with something strong. His vision was blurry, he was dizzy, and his whole body felt weak. Looking up, he saw the man and woman holding each other close, smiling down at him.
"Y-you tricked me huh," Batman asked, "I should have known better."
"Yeah, you should have Batman," the woman said, "but don't worry. We're all gonna have some fun later, so take a nap until then."
With that said, the drug finally got the better of him and he passed out. He woke up some time later in...........
