From Sympathy for the Devil, which is pretty much my favorite thing ever right now. Except that I listened to the third part of Zagreus while inking this, so there is a competition there.
It's from the Master's speech in Sympathy for the Devil, which is basically the saddest thing I've ever heard any of the Masters say. The Doctor, who's just arrived in Hong Kong 1997 from his second regeneration, gets into an argument with the Master (who's been there since '77) about interference, stemming from the Master's work for the Communist government in China. The Master says the Doctor only helps the 'right' sort of people, the Doctor says that he does what he can.
Master: "...I didn't see you at My Lai, Doctor, I didn't see you at East Timor. No interfering in Rwanda, I see. ...Pol Pot killed every doctor he could find, and none of them was you. I've been stuck on this miserable planet for 20 years, and I've done everything in my power to attract your attention. Where were you when the tanks rolled in in Tienanmen Square-"
I was listening to this on a long bus ride on the 11th around midnight, half-asleep, and I got this strong image of the Master seizing the Doctor's lapels, trying to force him to understand. So I drew it.
If you're interested, I posted a fuller discussion of the scene, with a bunch of preliminary sketches and studies of Mark Gatiss and Jon Pertwee on
my journal.
