Ghost was an immortal being, he had lived for years and years, unable to die from old age, spending years and years in his loneliness, although... you were always there.
Every life, every century, you or a version of you appeared to him, staying until you died in a horrific way, every time you promised to be together, every time the British tried to save you and every time you had died. Currently he had found you again, you looked different but he knew it was you, you both fell in love instantly and were together, his throat tightened when you dared to ask if you would be together in all your lives.
"In all our lives, my love..."
He murmured with teary eyes, turning to see you in bed, terrified of when the moment would come that you would die.
