The latest episode of Heroes:

'Peter receives a tattoo of the family crest from Caitlin, and Ricky tells Peter that he knows he's one of them. He tells him that they have no secrets among family, and places the box in front of Peter. Caitlin asks if he'll open it, but Peter mentions that Caitlin stopped him from killing Will. Peter wonders if the life in the box is a life he may not want. Caitlin asks if he likes who and where he is, and she suggests that maybe he should keep it that way, and the two kiss. As they kiss, the symbol appears from the tattoo before fading away from his skin.'
