Empathy

From The 4400 Wiki, a fan encyclopedia that anyone can edit.

Empathy is a promicin-induced ability that allows one to see the memories that cause strong emotions in other people around them. In these memories one can see events, names and even the feelings and thoughts of the people involved in that particular event. For this power to work, one must be conversing with the person.

Todd Barstow is a 4400 with this ability.
