As I should have said in "Chapter" 1, this is a motley collection of fanfic poems about Gollum and various alternative fates for him. And I don't own LOTR.
Here's one way I think the story should have gone:

Doom Rewritten

She waited in the shadows
Creeping all the way
Prowling in the nighttime
Sleeping in the day

Though lonely were his travels
He never was alone
From misty mere to arid sere
Behind him her eyes shone

And as he took the fateful fall
She snatched him from the fire
With fangs and feet and fingers
Kept him from his heart's desire

And though his life and spirit burned
She would not let him die
She held him through the searing pain
And soothed his every cry

And now he lives quite happily
Upon a distant shore
With she who is so like him
He is lonely no more
