This is Spike's thoughts expressed in a poem. Then a short story ending at the end to satisfy the rest of you.
Forever
Buffy.
You will never know,
know how much I love you,
how I stay awake during the day,
thinking about you, loving you,
missing you.
You left us all Slayer.
You left all the Scoobies and me,
Poor Nibblet, your sister,
technically,
you died for her and left us.
Slayer, luv, you will never know to the extent,
to which you killed me,
my memories blur, I can't go on,
I loved all you Summers women,
yet you never let me express it.
I loved you Slayer.
Always for Eternity.
Spike opened his eye to face the coming Dawn. As the morning sun hit his face he cringed. Opening his eyes he turned to face the approaching human shaped Dawn.
"Nibblet." He started, stepping toward her as the morning sun turned his bleached hair orange. "I...I'm not in flames and dieing and all."
Dawn took a step forward and suddenly slapped him. "Don't you dare even try to leave me too Spike." As the tears filled her eyes she launched herself at him and clung as the pair sunk to the ground and the tears rolled down their cheeks.
The sun glinted off their tears, it seemed to smile as Spike's tears slowly turning from blood red to clear.
