Here and there a person might pause for a short moment in a sentence such as: ... "Sir, you're on the bridge. How did you get here?" she replied. "I have no idea. I... was just in a storage room," his heart pounding as he remembered. ... Is an ellipsis the right thing to use in this situation, where it's not an explicit break in dialogue but a subtle pause during a phrase as if he's in thought? I've tried a hyphen but it doesn't seem right as it feels like it disconnects the two parts of the sentence. I thought maybe I should put a dialogue break such as, "I," he paused, "was just in a storage room," but that seems even more detached.
