There was a line or two cut from that ep, which I think you'll find interesting. When Wesley finds Angel drawing, he says something like "What are you doing"? To which Angel replies "Thinking. I like to think with my hands." Wesley looks at the portrait on Angel's lap and makes a "O o" face. He then says, "Sometimes just with the one (hand)?"

So yes. Angel draws Pron. A lot. And I'd love to see your take on that. Man, yes.
