Batman and Robin fight a gang but Robin gets injected with something that makes him seem high.
Robin/Damian-11
Batman/Bruce-27

~~~~~~~~~~~~~~~~~~~~~~~~~~~

Batman and Robin had been fighting a gang called the Fanged Wolves. (They aren't actually in Dc, unless they are, then proceed) It wasn't anything too serious. Just a drug trade.

Batman was fighting the leader while Robin took out the goons. This is one of the weakest gangs I've ever encountered. -tt-, Robin thought. He had already taken down half the gang without breaking a sweat.

That was until he was suddenly thrown across the room.

Someone had came up behind him, someone much stronger. While he was still in shock from the impact, something was injected into his arm.

Robin had already recovered from the blow and knocked down the guy who injected him with whatever. When Robin didn't feel anything after a bit he shrugged it off and kept fighting.

After Batman and Robin had changed to turn back into Bruce and Damian, Damian started feeling the effects. Bruce was already on the Bat computer looking through files. Damian was walking towards him when a sudden pain shot through his head. He winced and tried to shrug it off but it only got worse. Bruce noticed the sudden stop in his sons footsteps and turned around.

He took sight of Damian hunched over on the floor. "Damian. What's wrong?" Bruce asked. He got no answer. Then he heard a childish giggle. Confused, Bruce stood up and walked over to Damian. He crouched down to his level. Damian then looked up at him, his eyes dilated and a grin on his face.

"Woaahh, your hair is orange." Damian said in amazement as he reached for Bruce's hair.

Bruce gently grabbed his wrist and checked his pulse. It was fast, too fast. Bruce sighed. This had happened before with his other sons when they were Robin. They all had different reactions to it. Dick would ask millions and millions of questions, Jason would cry uncontrollably, and Tim would get aggressive.

Bruce tried to get Damian to stand up but he refused. "No! I wanna stay on the floor! The floor is my friend!" Robin said, followed by a giggle.

After awhile Bruce was finally able to get Damian off the floor but he was wobbly. Bruce just decided to pick him up. Damian had fun playing with the supposed cat with wings on Bruce's shoulder, while Bruce slightly chuckled at his behavior.

It wasn't long before Damian fell asleep in Bruce's arms. Bruce carried him up to his room and placed him in his bed. He turned off the light a slowly closed the door.
