Here we’re introduced to what will become one of Wegman’s trademark tricks. The twins in question blink, and one of them sways. First you notice what they’re doing. Then you mark the synchronization, and wonder how they do it, given that they’re not looking at each other or anything. (You wonder even more when the dog shows up in later films.) Then you realize that there’s an off-screen prompt going on. You speculate about what that might be, and Wegman never shows you. There’s a challenging and yet still reassuring, even encouraging epistemological pattern. Ontology too, for that matter. Given an answer, left with some questions. Feeling pretty good about the whole exchange.
