Angel Light

The bit of story at the side is vague, so I'll explain. Beast Boy died in an intense battle with Slade, and Raven was the last to see him. He said something just before he died about how he knew she could beat Slade, because it seemed to him like there had always been an angel there guiding her. And then he died. The Titans ended up defeating Slade (who posessed strange abilities they had never experienced before at the time) because Raven unleashed a side of her powers they had never seen before, in the form of orbs of white light rather than psychic energy.Raven is thinking of the white light as coming from the spirit of the departed Beast Boy, and so she believes that what he said was true, and he has been her angel all along.
