Through a Glass, Darkly

Obi-Wan had gotten to within an arm’s length of him. But it wasn’t...really Obi-Wan. He wore robes similar to his usual style, true enough. But they were splattered with something dark and wet. His hair was longer. His face was clean-shaven. He frowned across at Anakin, tilting his head to the side, and started, “Anakin, are you--”

OR, the one where Anakin gets lost in a universe that isn't... quite right and has to find his way home.
