"Go to her."
"She thinks you're dead!"
He didn't answer her.
"She thinks that you were blown to pieces – that all that's left of you is the book you proposed with-"
"I know that! I can see that!"
"Then go to her!"
"I can't do that...it's better this way."
"How? She loves you!"
"I know that! And I love her – and I can't do that to her. You know what I am, and all of the danger you yourself bring – and you would have me drop that on her?"
"...She wouldn't ever betray you. She would stand by you always."
He sighed. "I know. And that's what I fear the most."
"Why? You've been attatched to people before – had friends before."
"and they've all died, yes – but it would hurt her to know that she would leave me alone. I couldn't do that..."
"...Then you will let her be?"
"Never see her again?"
"...She'll never stop mourning you."
"One person to mourn the man who never dies..."
"It's not too late."
"Yes, it is. Harold Wren is dead, and she can never see him again.
He could feel the overwhelming sorrow she shared in the back of his mind, and could feel his warmth wrapping around his mind. He gasped as he could feel more of the pain of his wound again, but the tearing pain of leaving her was suddenly muted. "I am sorry."
"...It's not you're fault. It never was..." He hesitated for a moment, and then spoke aloud for almost the first time since he had woken up on the cot: "Goodbye, Grace."
AN: The Machine is basically always in his head. Inspired by the scene in episode I think 2x22 of Person of Interest after the bombing when he walks away and lets Grace think he's dead. 12-18-2015
