No one knew how to get back? That couldn't be possible -- unless this was a different dimension, but there would have be a spell of some kind to open up a portal home. He just knew that he couldn't stay here, not when he was like this and not after what had happened between him and Buffy barely a day ago. There was no telling what she would think when she realized he was gone.
He stayed with his back turned to her for a moment, working to get a hold of himself, but within a few seconds there was a flash of orange and a trashcan was on fire. A witch. The first person he'd come in contact with here was a witch. Did she know about vampires?
Slowly, Angel turned around. His features were still shifted, showing the ridges on his face and sharp fangs. After a moment his face went back to normal. "You're a witch." Angel had a mixed relationship with witches over the years, so it was hard to say how this meeting would go.
"And you're sure there's no way back." It was said more as a statement rather than a question. No doubt she'd probably tried to find a way herself.
