"Severus, please take her. The prophecy, something's going to happen, and I want at least one of them to be safe," Lilly pleaded. "James doesn't need to know you have her. Do it for me, Severus, do it for me."
"All right, Lilly, I'll do it. How are you going to keep him from knowing?"
"Madame Pomfrey will be there. She can tell him that she didn't survive the birth. I need her to be safe."
Severus smiled, "I hope she's like you, Lilly. I hope she's like you."
~A Few Months Later~
"Lilly, James," Madame Pomfrey said as the couple sat waiting to be handed their newborn children. "I'm sorry, but the girl didn't make it. Your son will be brought to you in a few moments. I truly am sorry."
"It's not your fault, Madame Pomfrey. I'm sure you did everything you could," Lilly told the older witch knowingly.
Just then, a woman about Lilly's age brought in a squirming bundle and passed it over to the Potters. Meanwhile, in another room, yet another bundle was being passed over to the dark form of Severus Snape. Inside was a small baby girl with Lilly's red hair and emerald green eyes, and Snape whispered, "I'll care for her, Lilly. I'll care for her."
