To prepare for the confrontation ahead, Hiro (Masi Oka) follows respected businessman, husband and father Arthur Petrelli (guest star Robert Forster) in the days before he “died” — to discover what drove him to create rival company Pinehearst and strike at Angela (Cristine Rose). Later, a moment unfolds where Sylar (Zachary Quinto), horrified and guilt-ridden, might have stopped his murderous pursuit of abilities — that is, if H.R.G. (Jack Coleman) and Elle (guest star Kristen Bell) had swayed from their monstrous assignment.
