A sly smile graced her lips as she chuckled, deviously, catching his hand and taking it in her own. He raced after her, not sure where she was going, only knowing she was disappearing in the blinding whiteness of their surroundings, and suddenly the world fell into a burning blackness, and he heard her roar shatter the depths, red flame suddenly alighting everywhere he looked. Hell. She stood, sword in hand, next to him and a million miles away, as a strange demon- god advanced on her, grinning… devilishly. Swords met, and fire flashed, and the demons rose to absorb her amongst them, brought her to her knees swinging, and her eyes bored into his…
He jolted awake from the nightmare, only to see that same pair of eyes boring down into his own. She seemed almost transparent, ghostly. Her face inches from his, pleading and reverent and afraid as he and he alone had ever seen her. He raised a hand to her face, but he passed through her body.
"You should not leave yourself for so long. They're seeking
you."
"I couldn't wait," she whispered apologetically. "I had to find you."
He kissed her then, not knowing what to say, and she suddenly seemed more solid, real. He clutched at her like a drowning man, and when he let go, there were tears in her eyes.
"I swear, I'll never let you go again." He whispered.
"Pray you never have to keep that promise," she smiled sadly, and turned to the side, as though startled.
Her apparition suddenly disappeared.
[A/N- okay, there's no way I could have explained this in context, so I'll explain it now. Severus is kinda dreaming. She did not actually apparate to be with him. It was more astral projection. There's a theory in shamanism that we live in both the spiritual and the physical plane simultaneously, and that the two are almost exactly alike, overlapping each other. So what happened is that she 'sent her spirit out' in search of him, and because the bond between their souls is so strong, she seemed almost solid, and he could see her. If they were not so connected, he might be able to sense her presence, but not physically see her or touch her. Hope that helps.]
