Extended Ending — “The Buggy and the Oath” Chill reaches the doorway; rain mist dances on the threshold. The Buggy rolls behind her, tyres squeaking on the tiles, lights flickering like worried eyes. > “No, wee one,” Chill murmurs, turning back. “You did your part.” " Beep- beep- bep- ,beep -Beeep" The Buggy hums twice, the tone rising — a digital whine that almost sounds like a bark. It bumps the doorframe stubbornly, chrome casing glinting. > Capt Ecco-G-Flex01 (through the comms): “He’s keyed to your pulse, Chill. Loyal circuitry— refuses to stand down.” “He’ll have to learn.” " Beep- beep- bep- ,beep -Beeeeep!" She kneels, presses her palm to the Buggy’s hood. A soft pulse of light passes between them — data and warmth mingling. > Capt Ecco-G-Flex01: “Transfer complete. His feed’s linked to my channel now. We’ll still hear him.” " Beep- beep-eep!" “Then you watch over him, Captain. He’ll keep the house breathing.” " Beep- beep- bep- ,beep -Beeeeep!" The Buggy’s lights dim to standby. It trundles back inside, settling beside the humming kettle like a faithful sentinel. Its lens blinks once — recording, remembering. Chill straightens, rain streaking down her new jacket. > “Guard the light, wee one.” "-Beeeeep hmmmm" She steps out into the storm. The door swings shut behind her, sealing the warmth inside. Through the chrome link, a faint sound: the Buggy’s soft mechanical purr, steady as a heartbeat. > Capt Ecco-G-Flex01: “Signal secure. Home’s protected.” “Then let’s move, Captain.” The streets of Brixton glimmer ahead — reflections of neon and purpose. Chapter 4 ends not in silence, but in loyalty’s hum. " Beee -hummmmm '' ( Soft bagpipes fade)
