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.

After reuniting Sylar and Elle, Arthur orders them to find Claire and bring her to him. Matt, Hiro and Ando team up together and follow Daphne to her hometown of Lawrence, Kansas to discover what she's been hiding. Meanwhile, Nathan and Peter Petrelli travel together to Haiti in search of the only man that can stop their father from destroying the world, the Haitian.
