Unbreakable Claire !

Hayden Panettiere said in an interview that Claire, her character on Heroes, is "pushing the limits of her ability to heal herself". According to SciFi Wire, "as she becomes more used to her powers, she'll start to use them unconscienly which leads to more of the kind of gore that was seen in early episodes of season 1". 
And according to Kristin, "the producers are looking to weave the various story arcs together more tightly". We know that "Niki leaves her family troubles behind and connects with the show's larger mythological mysteries", and she finally crosses paths with Claire !
