The day Damian left for Lazarus Island marked a milestone in your life that he would never have imagined the significance of. He was your best friend, or at least you considered him that way; but apparently you didn't mean the same to him. Because friends don't abandon each other.
Now that Damian was back in Gotham, settled next to his father, he finally took the time to care about you. And to his dismay, he didn't like what he found in the least.
"What the hell is wrong with you?" Damian growled, shaking you to make you pay attention to him.
He had just beaten up a guy who was trying to force himself on you, taking advantage of how dazed you were from the drugs you took. But you didn't even know what was happening, too drugged to pay attention.
Damian was furious, his eyes seeing red as you smiled like you were on cloud nine. You cared little about his annoyance, since he was the only one to blame for the fact that you ended up like this, adrift, wandering in search of happiness in the most remote places.
