T3, E6: Impressed by his sudden ruthlessness, Villains Knox (guest star Jamie Hector) and Daphne (guest star Brea Grant) bring Hiro (Masi Oka) -- among others -- into the Pinehearst fold, and give him an assignment. With Angela (Cristine Rose) and the Company paralyzed by recent events, Peter (Milo Ventimiglia) goes directly to Pinehearst for answers, and irrevocably changed by the shocking meeting. Meanwhile, Claire (Hayden Panettiere) and her mother Sandra (Ashley Crow) attempt to free Meredith (Jessalyn Gilsig) from the thrall of escaped Villain Doyle (David H. Lawrence XVII), who has the ability to take mental and physical control of others. Later, Nathan (Adrian Pasdar) brings Tracy (Ali Larter) to Suresh (Sendhil Ramamurthy), hoping he can shed light on the surprising origin of their abilities. Jack Coleman, Greg Grunberg, James Kyson Lee, Zachary Quinto and Dania Ramirez star. David Anders, Alan Blumenfeld, Robert Forster and Blake Shields guest star.
