She's dead because of her

Emma and Kieran are kissing in his truck and her shirt comes off.

I'll never be able to touch her again

She tells him that she hates her scar because it makes her ugly.

I'm stuck with this insignificant reflection of her

"It makes you more beautiful," he tells her.

I miss her

Little does she know what he means, he sees Piper in her, nothing that made Piper beautiful is in Emma, but they are sisters and this blonde resembles his love. She'll never be Piper and Piper is gone forever, but not when he touches this girl…or…when he touches her scar. The last thing Piper left on her sister and the only thing she left Kieran.

I need her

When Emma resembles Piper, she's beautiful to Kieran, but thanks to that scar, she's more beautiful.

She was truly beautiful

He looks at that scar and he sees…his Piper.
