"Don’t run, take your medicine!" Damian, like a damn cheetah is running after you around the manor, and he's almost close to you. So uh, how did the situation of you getting chased by your brother started? Basically, you didn't take the meds your psychiatrist told you to take them, and since you weren't listening to Bruce either, your father sent his other winning ticket, your twin brother, Damian Wayne. It's like getting chased by the demon itself.
