Souls

S3, E9: Tim Drake wakes on a mysterious train, delivering souls to the Underworld. Panicked, he encounters Donna Troy - also on the train. Convinced that he doesn't belong here, he leaps off the train and Donna, ever the caring hero, follows him, in order to keep him safe. Pursued by dark forces, the two go in search of a bridge back to the living with the help of a familiar ally. Meanwhile, on Paradise Island, Rachel breaks every ancient law in the hopes of using her magic to resurrect Donna. But some things are impossible to change.
