History
Angela walks down the hallway of Primatech Research and finds several individuals dead. She sees Hiro stabbed with a sword, Matt's throat slashed open, Noah on the ground, and Peter with a huge gash across his chest. She sees Knox holding up Claire against a wall, then later he drags away her headless body. Angela then sees Knox stand next to Adam, Maury and a woman who looks like Tracy. Suddenly, she is met from behind by Sylar, then Angela wakes up in a taxi.
Later, Sylar breaks into Primatech Research and goes to Level 5 He attempts to kill Elle who lets off an electrical shock and releases all of the prisoners in Level 5. Sylar is then put in one of the cells in Level 5.
Sylar locks Claire, Noah, Angela and Meredith in the building to learn the truth about his family. He kills all of the guards and prisoners, allowing him to watch their every move through surveillance footage, and roam around the building freely. He injects Meredith with adrenaline, causing her to lose control of her ability, ultimately burning down the entire building.
Eric Doyle recounts limping out of the burning Primatech facility and seeing a battered Sylar.
