Armed with H.R.G.'s old files and a taser, Claire attempts to take down her first target -- Stephen Canfield, a Level 5 escapee with the ability to create black holes -- unaware that others are closing in. Meanwhile, in horror, Peter flees from all the death and destruction in the future, only to grimly discover how deeply the experience has changed him. Frustrated that Adam Monroe didn't get them closer to the formula, Hiro takes a stab at becoming friends with Daphne and new associate Knox, much to Ando's dismay. Later, Suresh's urge to correct research errors puts Maya, among others, in a sticky situation. Linderman advises Nathan to stick by Tracy, seeing that they could accomplish great things together. In Africa, Matt sees his vision of happily ever after destroyed.

Trapped and terrified, Nathan and Tracy fight for their lives against a much-changed, monstrous Suresh to free themselves, Maya and the doctor's other "test subjects." Elle returns, with a shock for Claire and her family. Meanwhile, aware of Peter's ruthless take down by her rivals at Pinehearst, Angela reaches out to convince Sylar to save his brother. Since he won't sign up with the Villains, Daphne is ordered by her boss to go back and kill Matt -- or be killed herself. While in awe of the African precog's power, Hiro still questions Usutu's advice on how to best face his gathering opponents.
