Rumlow is, apparently, a man who will not be moved by reason or by bartering - exactly the sort of person Sigma has a hard time dealing with. He watches the other man advance and must stare at him in confusion before he realizes he is being threatened. He would kill him for reading his mind? That was usually not the reaction his powers begot.

Sigma has no choice but to retreat somewhat, to take a step back before Rumlow comes within arm's reach. "I..." He is still blinking spots back from his eyes, where his sight is returning from the doomed world to the present one. "I can predict death," he blurts out, which is not quite the truth, but the brevity might save his life. Now Sigma steels himself, plants his feet at shoulder's width apart, and holds out his hands. "Stop. We do not have the time for this. You are going to die if you don't listen to me!" It was another quick half-truth, but Sigma feared what might come down those halls more than a broken neck.
