I have to think that rather than a serial monogamist, Donald Mitchel was an exploiter, not only for his art but his peccadillos...
It was not a remarkable story; two men, one experienced, the other naïve and inexperienced. For one it was a pleasant diversion and a means to an end; Donald Mitchell seems to have been what Mother calls a serial monogamist. True to the current person, but liable to change. Greg, however, was the focus of Mitchell’s intense artistic scrutiny as well. This created expectations that Mitchell had neither ability nor intention to fulfil. The result was some fine art and one fucked-up kid.
