Birthmark

It's Raven's birthday, but she is far from wanting to celebrate. But before Robin can learn why, the Titans receive a distress call and go to check it out. When they get there, they are greeted by none other than Slade, back from the dead. But Slade seems to have new powers along with a strange red mark on his head and he has a message for Raven that he is going to deliver, no matter what.
