In "It's Coming", Peter and Claire get into an argument about the future that Peter witnessed in "I Am Become Death" in which Claire becomes a ruthless killer herself, with Claire trying to prove otherwise. They are accosted by Knox and Flint (who is still unaware that Claire is his niece through Meredith). Believing them to be after Peter, Claire tries to hold them off, until they reveal that they actually came for her. Claire is surprised that Knox knows her name and ends up captured by the two villains, but she is saved by Peter, who overheard her shouts: Looking at the gas pipe, which was leaking, Peter warned Knox and Flint that he didn't need his powers to stop them, and provoked Flint into unleashing his pyrokinesis, which ignited the airborne gas, buying Peter and Claire time to escape. The biological uncle-niece team later arrive at Primatech, where Matt Parkman attacks Peter for teleporting him to Africa. After Peter convinces Matt (via thoughtspeak) that it wasn't him, but rather Future Peter, Matt and Daphne Millbrook take them to Angela Petrelli's room, where she is awake. Nathan arrives a few moments later, and Angela reveals that even though Pinehearst has both halves of the super-ability formula, a third element is needed; "a catalyst hidden in the blood of a human host," as Angela puts it. Claire recalls Sylar's attack on her and points out that Sylar had called her "different...special" after noticing something unusual about her brain; using this information, Claire theorizes that she is, in fact, the catalyst.
