To prepare for the confrontation ahead, Hiro explores what forces - and familiar faces - helped twist Sylar, Flint, and Arthur Petrelli into Villains.

To prepare for the confrontation ahead, Hiro follows respected businessman, husband and father Arthur Petrelli in the days before he “died” — to discover what drove him to create rival company Pinehearst and strike at Angela.

Later, a moment unfolds where Sylar, horrified and guilt-ridden, might have stopped his murderous pursuit of abilities — that is, if H.R.G. and Elle had swayed from their monstrous assignment.

Finally, under the wing of Company man Thompson, agent-in-training Meredith watches her new life go up in smoke, following the arrival of her hot-headed brother.
