Jack told the Doctor the whole story: his past history with Hart, the incident with the ‘cluster bombs’, Hart’s return and the devastation of Cardiff at Gray’s orders. He admitted his guilt over what had happened to Gray and explained that the punishment his brother meted out on him was justified.
“I deserved it. I let go of his hand.”
“Oh Jack, you are so wrong about that. Your father should never have placed responsibility for protecting your brother on your shoulders. You were still a child yourself; he should have protected you both. I’m so sorry, for all your losses.”
When work on the drone was completed, the Doctor grasped Jack’s shoulders.
“Forgive yourself, Jack. It’s time you let go of the past. Remember when Rose convinced me to let you stay on the TARDIS?”
“Those were good times, Doc; some of the best. You turned my life around, ya know. Whatever good I’ve done is because you and Rose believed in me.”
“I wasn’t sure but Rose, she was convinced that you were a good man. You just needed a little help to see that in yourself. She was right. She always saw more clearly than me.”
