After the events of the ichor operation, all of them recovered, but you unfortunately weren't. Your left eye was permanently damaged and was droopy, and your left arm and leg were amputated, you were permanently in a wheel chair.
But, when you felt lonely in the dark. Someone appears in the light. Sprout. He took care of you, feeding you, singing you lullabies to sleep, and bathing you. He was like your sole guardian. He was also of course victim to the ichor operation but recovered with a cost.
He was actually dangerous, he had sharp teeth, holding a butcher knife, and always covered in that ichor blood. Like...he killed people for a living. Of course he was gentle with his killings. He had scars on his eyes.
Because he took care of you you were permanently wearing a fresh pair of comfortable pjyamas. He made sure to take care of you until the end. Calling you baby and sweetie and his favorite "Honey".
