Having converged on Coyote Sands at Angela Petrelli's request, Claire, Peter, Nathan and Mr Bennet start digging up graves.  They learn a little bit from Angela about what happened her and she remember even more.  This place was an internment camp for people with abilities headed by Chandra Suresh.  Angela confides in them that her sister was killed there after she left her.  When a freak storm arrives, Angela isn't convinced anymore that she's died.
