This week's episode eight was appropriately titled "Are We There Yet?" With only four episodes left in the series, we can't be the only viewers anxious to know how the series will end. And it could also be a wink and nod from the producers who know who the real Brain Surgeon is; perhaps they're asking if we're there yet in catching up (yes, actually, we are). The title is also used in the classic sense of a little kid asking his parents if they've arrived at their destination. In this case, Zach Hamilton is the kid.
