What was Westerburg's impression of Chris? into the wild chapter 3​

Westerberg describes Chris McCandless to Jon Krakauer, who the reader knows has come to interview him about McCandless. Krakauer relates that Westerberg, then overseeing a barley harvest in Montana, picked up McCandless while he was hitchhiking. Westerberg remembers him as restless and handsome, with a sensitive face and a lean physique. He mentions that women would likely have found him attractive, but also describes his face as alternating between animated and slack. Alex was engaging and friendly.
