"Why'd we have to tell him? He'd make a big deal out of it in a smug annoying way," the reason why the Doctor was easy to be with was that he didn't act like John was a child learning to look both ways when crossing the road whenever he did the right thing. It got under his skin, the way Jack was with him, and it made him want to do worse and worse. The Doctor didn't overly draw attention, he just let him do it. It was nicer, easier to deal with. And besides, it was fun taking the piss out of the Doctor and beating a Dalek all in one go.

Even if John liked him, he always overcomplicated his life. In a horrible sexy way. "He doesn't feel for me. I'm nostalgia. I'm an old reminder of his past, a bad influence. He can go fuck himself," John said drowsily as he stretched his arm out further. His eyes were starting to ache but he stubbornly kept them open, ignoring the horrible mucusy gunk building up in his chest, causing him to cough violent. "I don't change, remember? I relapse. It's not worth making of note of, Doc. Don't get your hopes up."

He wasn't about to change after a few good deeds.
