Nevermore

S1, E6: When a battle with Dr. Light overwhelms Raven, the Titans discover a side of their mysterious friend that they've never seen before--her temper. After Raven's creepy tantrum of crackling black energy leaves Dr. Light begging for mercy, Beast Boy isn't quite sure how to treat her, and he makes her feel even worse about what happened. But when Cyborg takes Beast Boy by Raven's room to apologize, she's not there--so Beast Boy drags Cyborg in to snoop around. Beast Boy finds a mysterious mirror, and when he picks it up, Beast Boy and Cyborg find themselves transported to a strange nightmare world that's somehow connected to Raven. Will Raven be able to guide the boys home or will her personal issues destroy them all?
