Matt's on the floor with his son when Angela calls him. Apparently he told her never to call, but she says there's a problem with that thing he did six weeks ago. She says Sylar's beginning to emerge again, and Matt says that's because he is Sylar. She says that's not true, because Matt erased Sylar from him; she saw it happen. She needs him to fix it, by going back into his mind and erasing more or upgrading it or whatever. For someone who's so sure of what she saw Matt do, she sure doesn't know crap about what it is he did. Is this the first time we have had a lack of continuity between two sentences in a single scene? Oh, probably not, but still. Matt's not doing it, because he stopped using his powers. He's done. He's out. Angela says there's no such thing as out for people like them. He disagrees and says this is her problem, wishes her luck, and hangs up. Then he looks worriedly at Baby Matt.
In his office, Sylar-as-Nathan looks thoughtful as he reaches for his cup of coffee... which comes over to him, because the Sylar power is seeping out. He looks amazed, and tries to do it again. He can't, but he does shoot some electricity out of his hands. He's like: WTF?!
