We looked at each other, for a long strange moment that I’ve never forgotten, actually, like two animals meeting at twilight, during which some clear, personable spark seemed to fly up through his eyes and I saw the creature he really was—and he, I believe, saw me. For an instant we were wired together and humming, like two engines on the same circuit.
animals or electricity? very nearly a mixed metaphor. seriously? Also would like to point out that engines aren't ON a circuit, but are comprised of them, so really should be "two circuits in the same engine."
