[The Doctor] pointed at Barbara. “Talk to her.”
"Oh, she’ll be all right," I said, admiringly. "It was traumatic at the time, but she’s tough. She’s strong that way."
The Doctor smiled at me. “That’s not what I meant.”
I looked at him. Searched his face. Of course. Of course he knew. He always did, wily old devil. “Maybe soon. Definitely.”
"Don’t wait too long, my boy. These things can fade. We all have opportunities we let slide. You don’t want to live your life regretting chances missed."
I nodded. And I knew.
"Well," he said, "in your own time."
