Harry's sobs tore at Lily's heart, as there was nothing she could do to mend the wound of the loss he'd lived with for Merlin knew how many years, no quick fix with a wave of her wand that would make it all right again. All she could do was hold on to him as fiercely as possible.
You saved me.
For him to be alive, someone had obviously had to save him, but she hadn't known who. Until now. And knowing it, she would have, again and again if necessary. Giving her life for her son hadn't been a conscious, premeditated choice that night – one lived just recently for her – but if it ever was, the choice would still be the same.
When he grasped her shoulders, she looked up at him, heart breaking even as it swelled with pride. The prophecy hadn't been wrong, and Lily didn't intend to take any credit for whatever he'd done to defeat Voldemort – though sense and knowledge of magic offered immediate options as to how, such as the Killing Curse rebounding.
"That was the end of him then, tonight – that night? "Your Dad." She paused. "Oh, Harry, wait a moment. I'll get James right now." She looked around, noted the address plaque near the gates and then out came her wand and off went the Patronus once more, the doe dashing off at far greater speeds than before to find James and bring him back to this place. Lily hoped he was close by, despite the previous intent to spread out, because he needed to be here now.
