Tommy loved Grace, really loved her and her betrayal hurt. He was used to being the one that broke hearts in a twisted way it was refreshing to have the roles reversed.
In some ways it was funny that he wasn't aware that he still had a heart until she broke it.
His beautiful Grace, who had something dangerous and deadly burning in her eyes tore out his heart and sang a sad song while doing do it.
Maybe one day when his heart mended and started to beat again, he could forgive her.
