A short one shot idea I had after drawing Lily and James fan art.
A Mother's Love
There were many thoughts going through Lily's head in the last minutes of her short life. But one that had the strongest hold on her was regret. She knew from the moment James yelled for her to take Harry and run that her life was over. She heard Voldemort yell out the killing curse and she could feel more then hear her beloved James body fall to the floor, devoid of life. Her heart broke but she knew that she couldn't stop. She rushed into Harry's room and reached down to lift him from his bed. He was awake and staring at her with big green eyes that were so much like hers. She pulled him tight in her arms and whispered reassurances despite the fact that he was silent and still. She had time as Voldemort slowly made his way to the second floor of Godric's Hollow, to realize what hers and James' death would mean. Poor Harry would grow up without them. He would not know how much he meant to them. He would never know that he was the best thing she had ever done, her and James' miracle. She also knew that she would never see James again and she regretted that more than she could bear. James was the love of her life and the few short years they had had together were the happiest of her life. They were meant to live and see Harry grow into a man like James; strong, brave and loyal. Tears shown in her eyes as the door was blast open. She clutched Harry tighter, rocking back and forth in an automatic gesture.
She was barely aware as Voldemort told her to step aside. She would never sacrifice her son for the sake of herself. She was aware of begging for him to spare Harry, but her mind was filled of images of happy memories. Harry playing with his 'Snuffles" plush toy Sirius had got him his first Christmas; James spinning Harry around while both laughed themselves to tears; she and the marauders celebrating Harry's first birthday in their small home. She imaged what Harry would look like when he went off to Hogwarts for the first time, just like James in his first year. She imagined him happy and laughing with friends by the great lake, as she, James and their friends had. But she realized with a smile as the fatal green light came barreling towards her, he would live and he would do all those things. And even if she and James weren't there to see it themselves, Harry would be okay because he was their son and he would have their unconditional love. As the light struck her, she gave one final squeeze to her beloved boy and she fell to the floor cradling his soft body, a smile on her face. Harry was loved.
