Do You Realize - that you have the most beautiful face
Do You Realize - we're floating in space -

He is still here, even after all the therapy they suggested. Like a stain, he remains, forever captured in the depths of her mind. He had been seared to her flesh. No matter how far he is, she will always be drowning in insanity. It is a pain like no other. Sometimes, it bears a resemblance to his face, a pale reminder of existence. The feelings are cold now and have moved away. Such are the remnants of a broken relationship.

Do You Realize - that happiness makes you cry
Do You Realize - that everyone you know someday will die

She was present at the wedding and watched him wed. The fingers clutched in her hand bloodied though she is numb. She wanted them to feel the cold twist of metal that spilled red. Starfire was covered in it. The white dress and veil was seeped, like the blood red of a rotted rose. The smear of despair and broken fragility smothered them all. And their faces blurred in her vision.

And instead of saying all of your goodbyes - let them know
You realize that life goes fast

It has become an obsession. But the pain never truly goes away. She feels the knife plunged in her chest. Only nobody hears the desperate call for help. She finds her fingers wrapped around the photographs of him and his beautiful wife and their children. She watches their faces burn in her mind and then puts them away again. The solitude can never be pieced together and she is helpless. He holds the cold metal in his hands.

It's hard to make the good things last
You realize the sun don'-go down

Sometimes she awakes from the visions and almost expects to feel the warm red liquid drip from her hands. She knows it is only a matter of time until she is consumed by it all. And yet there is nothing she can do. Nothing can bring her back. Until the night when she slips in quietly. Cold fingers reach for the tender skin and the blade cuts in. She avoids the faces of the children, not wanting to see what she could have had.

It's just an illusion caused by the world spinning round
Do You Realize-Oh-Oh–Oh

Next, she approaches their bed. The knife moves, her hands shaking as it cuts. Something inside her is satisfied, a twisted pleasure. Staring at her are the blank eyes of her teammate. She avoids the dull green orbs and turns to her Robin. She trembles and peels the sheet back from his face. His eyes widen, shocked by his punctured chest. Her hands cover the gushing wound and are tainted. Stealing his last breath, she grabs the metals and twists.

Do You Realize - that everyone you know
Someday will die –

She calls it therapy.
