[Jack's eyes shine with unshed tears and his answer is a mix of longing and grief. If he could give the Doctor or Rose that he would in an instant even though he doesn't want it. He knows the joy children can bring and it isn't their fault Jack's experiences had been so bad. He strokes the Doctor's hair gently and his touches turn from desperate want to gentle love. It isn't the Doctor's fault either that Jack is old and weary. It's what happens when you are an immortal on the slow path just trying to do the right thing.

His answering mental hug is full of all the things he can't say out loud to the Time Lord and others in his life who aren't here anymore.]
