This is set in my main AU and way into the future.
"Emily, stay strong my darling. Please. Wake up." Aaron whispered, holding her hand, hearing the beeps of the life support machine.
She was dying; it was the end of the road and her cancer had become too serious. It had come back. She was terminal. Aaron just wasn't ready to say goodbye – to turn the machine off. But he knew that it was what she would have wanted. She'd told him. Not to leave her there; dead but not quite.
Not to leave her – with no life. He knew that if she didn't wake soon, it would be time for her to go. He had to say goodbye.
He thought back to when Emily was admitted to hospital a few days before, having a seizure. Scared the living daylights out of him. Scared the living daylights out of Harry. He was 17, and was home with Emily that day. The day she had a seizure and never woken up.
Jack was away on a case, he had joined the FBI. Inspired by both Emily and Aaron. He hoped to one day be in the BAU. Flying over as soon as he could he said his goodbye's to Emily, it hurt. She was a mother to him for so long after Hayley's death. He couldn't spend long there it just hurt too much.
But Aaron, he sat there, stayed there with her. Not wanting to leave her, not wanting to let her go. Having to decide. He couldn't lose another wife. The loss of Hayley still hurt to this day. He was too late to save her – he got too involved in his job to save her and there was still a piece of him that felt guilty for that.
He couldn't carry the burden of Emily's death too. Although he could not logically place the blame on himself. He knew he would and it would hurt greatly. But then again he felt bad leaving her on life support. Just for him… just so she was still there…
Giving her one last kiss on the cheek, avoiding all the wires. He had decided it was time, time to let her go.
Phoning Roxanne so she could give one last goodbye before she left he sighed. This was it. The end.
"Bye Mom." She whispered, giving her a kiss on the cheek. "Can I stay or do you want time alone with her while she goes?" Roxanne asked Aaron.
"Stay." He responded simply.
The life support was turned off. Roxanne held her mother's hand, waiting for her to go. Aaron stroked her face, not holding back the tears. "I'm going to miss you darling." He told her just as she went.
