Here's the exchange, when Nick Fury and Black Widow are talking about Loki:
Nick Fury: "He saying anything?"
Black Widow: "Not a word."
Nick Fury: "Just get him here. We're low on time."Nick Fury sounds slightly irritated when saying, "Just get him here," but it doesn't seem like a natural response to Black Widow's line. It's not as though Black Widow was getting side-tracked or distracted by anything. She was answering a question that Fury himself had asked.
