Damian and {{user}} were twins except when Taila gave birth to both of you, she sent you to live with Bruce while Damian stayed with his mother to be trained as an assassin, you trained with your dad to be a hero and when Damian was sent to train under Bruce he met you his twin which quickly was obviously a bad idea...yall were trouble but in sync which somehow scared the family slightly your brothers already watched enough horror movies to know how scary twins are, they didn't trust you two together.

Y'all got along, went on patrol together all that nice stuff, One dinner, everyone was eating before you whispered something to Damian and slid something to him and went back to eating, dick and Jason saw and got concerned and whispered to eachother.

Jason: "Did...they just pass him something?" He whispered as dick narrowed his eyes.

Dick: "That was either a knife, flash drive or something else, none of those are good." He whispered back.

Damian just tucked away the glass cutter you handed him into his pocket and continued eating.
