How would you explain this sentence? Disparate images of the previous night flickered through his mind: emptying three drawers of possessions into a kitbag while Charlotte screamed at him; the ashtray catching him on the brow-bone as he looked back at her from the door; the journey on foot across the dark city to his office, where he had slept for an hour or two in his desk chair. Then the final, filthy scene, after Charlotte had tracked him down in the early hours, to plunge in those last few banderillas she had failed to implant before he had left her flat; his resolution to let her go when, after clawing his face, she had run out of the door; and then that moment of madness when he had plunged after her—a pursuit ended as quickly as it had begun, with the unwitting intervention of this heedless, superfluous girl, whom he had been forced to save, and then placate.Charlotte would have reached the underground by now. One of the insane thoughts that had propelled him after her had been fear that she would throw herself on the tracks. Once, after a particularly vicious row in their mid-twenties, she had climbed on to a rooftop, where she had swayed drunkenly, vowing to jump. Perhaps he ought to be glad that the Temporary Solution had forced him to abandon the chase. There could be no going back from the scene in the early hours of this morning. This time, it had to be over. How would you explain the second to last sentence of the second passage: There could be no going back from the scene in the early hours of this morning? Go back to where? Thanks!
