Parkman goes back to Sylar and says he was holding back and is motivated now. He touches Sylar's head and we flash on him with Elle and with his mom, and then killing many, many victims. When Parkman finishes, Sylar doesn't feel different, so Parkman asks him to try something on him. He can't do anything, so Sylar says he did it! Parkman then says the powers aren't gone; they're just buried where he can't get to them. He says he knows exactly what scares Gabriel: Being alone with his immortality. He says he's trapped Sylar inside his brain, alone in a nightmare. He says the best part is that once Matt leaves, Sylar won't remember any of it and will live every empty day like it's real. Sylar tearfully says, "You said you'd help me?" Parkman says there's still some Sylon left in him, he guesses, because he lied. He tells him to enjoy hell, then he seems to vanish as we get various flashes of Sylar saying "Parkman. Parkman?" I have no clue what even just happened there. It makes absolutely no sense. So, he made Sylar's brain think he's alone with his immortality? Wasn't he anyway?! I mean, wasn't that the point?
Parkman basement. Matt's building a brick wall in front of Sylar, all Edgar Allan Poe or Oz, whichever the writers may have read/seen (I'm going to guess they watched rather than read, since I don't think the writers of this show are big on reading or writing, sadly). Time lapse as he builds and builds the wall. When he has most of Sylar covered, other than the head, Peter knocks on his door. Sam, annoyed, heads upstairs to answer. Commercials. I wonder if anyone actually plays the Heroes theme games at NBC.com? Also, Parenthood: What a great cast. What terrible promos.
