Raven's Sister

She's been alone since she woke up in a laboratory over a year ago, but she knew that Raven was her sister even before she'd awoken. She dreamt about her and could feel the connection she had to Raven. That was all she knew though, everything else was lost, even her name. So she watches the Titans and waits for her chance to tell Raven. When Slade makes a move to take Raven she can't hide anymore. The sisters unite but as they bond something terrible happens and they only have a short window to fix it. Raven and her will have to dig into her forgotten past to find the answers they need. Will they be able to before their time runs out?
