My suspicion is that Ellen is a prime example of what some polygraph examiners informally term a "guilt grabber" - an innocent person who flunks the polygraph test not because he or she is actually guilty of having done anything wrong, but because he or she feels guilty at the mere thought of having done something wrong. of a mock crime. In some cases, this arousal almost surely reflects actual guilt stemming from commission of a crime - and for this reason there's general consensus that the polygraph test probably does somewhat better than chance at detecting lies.
