P.S. : The version of Damian Wayne used in the story is an older version of the character, basically this takes place years after Damian was supposed to be killed.

'' How did you even come up with an idea like this!? Seriously! Out of all possible options you pair me up with her!''
Damian protested loudly to his father as he pointed a finger towards Barbara, who, at her turn only gave an annoyed look at the kid standing in front of her.
'' How pathetic..one thing is for sure, I'm not going to babysit this kid, if he dies than that's just bad luck, so you better stay out my way''

A slight smile covered Barbara her lips as she thought back to her first meeting with this person, her eyes moved away from the building they were looking at and instead moved to the man next to her.
'' What're you smiling for?'' Damian responded without averting his eyes from the building.
It was clear how much he had grown up since their first meeting, both in age and personality, yet sometimes she disliked him the way he was now, so cold and distant, where he used to be stubborn and arrogant he still cared greatly for his comrades and that was visible from time to time.
'' Just remembering the past, nothing else...'' Barbara replied softly as her eyes moved back to the building again.
'' There is no use looking at the past. We can't change the things that have happened, it is the future we can change...'' Damian answered coldly as he suddenly got up from his seated position, '' Found him''
He leaped off the building and easily crashed through the window of the building located on the other side of the street, even before Barbara could arrive at well he had already dealt with the armed thugs in the apartment.
'' You're getting slow, could be fatal in battle'' Damian responded coldly as his glaring eyes moved towards Barbara.
'' Like you would care about that'' Barbara mumbled, expecting him not to hear what she said, yet he did loud and clear, the cold look in his eyes made place for something else but his intensive training quickly got him over it.

'' So what information do we have about Joker's location?'' Bruce asked when all of the members had returned to the Bat-cave.
'' The coward has hid himself inside the city, we're still unaware to pinpoint his exact location, don't worry father, I'll find him for sure, let's go Barbara''
Before either Bruce or Barbara could object he had already left, Barbara quickly hurried after him.
'' So how are we going to find him? Do you have anything you didn't tell your father about?''
Barbara asked Damian with a slightly worried look on her face.
'' We? We aren't going to find him'' Damian stopped walking and turned towards Barbara as he narrowed his eyes, '' I don't need your help, if you can't keep up with me you're just dead weight to me, now leave''
'' But Damian, we-..''
'' LEAVE! , I don't need any help of a girl!'' Damian suddenly shouted out to Barbara her surprise, a strange mix of disappointment and anger rushed through her veins.
She clenched her fists as she looked at Damian who walked away from her.

For days there was no form communication between Damian and any of the others, Barbara had slowly started to become nervous after the sixth day of unknowingness.
Bruce had gathered all of the others to the Bat-cave to set out a rescue team after he had worrying video tape from the Joker.
It showed Damian heavily beaten up while Joker's maniacally laughed as he placed a bomb on the person's lap.
Barbara most of all was shocked by it, it was her fault that he was in this position right now, if she had just acted on that moment things would have gone differently.
'' What is his location?'' Her eyes rapidly moved over the video trying to find any clues and when she did so she rushed off to the place.
Yet seconds before she could enter the building it exploded, her eyes widened and she dropped down on her knees, seeing the building go up in flames.
'' Nooooo!''
Tears quickly started to flow down her cheeks as the ashes of the burning building started to fall down around her, she had lost all strength in her body.
Frozen in fear and anger, she was angry, she hated herself, if she had just been a few seconds earlier, if she had just been faster!
