The heart necklace Claire Bennet wears is an open story book for the clairsentient.

Clairsentience is the ability of a telepath to see the mental impressions left on objects, effectively seeing the past through the eyes of whoever left the mental impression. Clairsentience is the ability to perceive the mental impressions left by people on physical objects by touching them. However, it can also be used to feel forcefields or any other intangible force that would be otherwise imperceptible. The DNA Alternate may have difficulty adjusting to life when every contact can provide information overload. This ability does not expand to the ideas and thought processes of those who touch it; only to actions in relation to the object.
