Bee had no destination in mind when she used her Glinda-the-Good-Witch powers to escape Tim. She just needed to get away. She finds herself, somewhat appropriately, in a bathroom. She doesn't pause to note the other presence there, just slides immediately to the floor and buries her face in her hands, trembling and whimpering softly. Pathetic. She left him behind, to contend with whatever that is he's becoming. He might still be in there, fighting, frightened, and she left him.
