And tonight’s episode is:
Homecoming. As H.R.G. (Jack Coleman) tries to protect his daughter by any means, Claire’s (Hayden Panettiere) high school homecoming turns into a frightening night.

Elsewhere, Hiro (Masi Oka) travels back in time to right an upsetting wrong and as Niki (Ali Larter) puts a goal in sight, Micah (Noah Gray-Cabey) spends time with his dad (Leonard Roberts). Still experiencing strange dreams while in India, Suresh (Sendhil Ramamurthy) learns of a boy that might pull him back into his father’s research. Greg Grunberg also stars.
