This is a poem about Snape's last words 'Look at me," and what he and Harry may have been feeling during the brief amount of time they spent looking into each other's eyes.
Enjoy~
He wanted to see her, go back in time
He was coated in blood, nearing the end of the line
As if to grant a final wish, you entered through the wall
Your eyes, her eyes were what he needed after all
You walked to his side and took a knee
And he gave you his memories
"Look . . . at . . . me," his dying words were
Your eyes met his and he saw her
But the happiness, the love that he'd once seen
You take it away, you show him green
But you had his past in your hand, you would know the truth
How his love for your mother protected you
How he fooled the Dark Lord that took her from you both
And the death of Lily Potter formed an unbreakable oath
You did not yet know this, so as you stare
You unwittingly refuse to show Lily there
Though, for him, it was enough, to see her alive
The only part of Lily that survived
Through you he saw her, yes, he saw her through you
And he vanished thinking, "Just green will do"
