Major spoilers here, if you haven't seen all the episodes so far.
In the episode, "The List", I thought for sure I heard Mr. Bennet say there were 36 people on the list.
Here List of Heroes so far:
1. Claire Bennet - regen
2. Isaac Mendez (the artist) - can paint the future (Precognition)
3. Nathan Petrelli - flight
4. Peter Petrelli - can use other's powers
5. Hiro Nakamura - manipulate space & time
6. Niki/Jessica Sanders - super strength/alternate personality
7. Matt Parkman (the cop) - reads others' thoughts (telepathy)
8. D.L. Hawkins - phase through things
9. Sylar (Gabriel Gray) - absorbs others' powers? Now telekinesis (tried to kill Eden; who else did he kill?)
10. The first guy Sylar killed (Brian Davis?) - telekinesis
11. Eden McCain (Mr. Bennet's assistant) (almost killed by Sylar) - can make others do what she wants (power of persuation)
12. the Haitian - erases memories and can dampen others' powers (mind blocking)
13. Meredith Gordon (Claire's mom) - pyrokinesis
14. Theodore "Ted" Sprague - Radioactive man
15. "Claude" - Invisible man
16. Sanjog Iyer - the kid who invades dreams
17. Charlene "Charlie" Andrews (the waitress) - could learn things very quickly (total recall)
18. Micah Sanders (Nikki & DL's son) – technopath
19. ? Molly Walker (little girl) – attacked by Slyar; saved by Matt (the cop); Sylar went after her again later
20. ? Molly's dad (Slyar scalped him)
21. Hana Gitelman – Electronic data transcription (new)
Granted, number 19 and 20 are questionable. And I think there are a couple others Sylar killed that we haven't been told about.
I don't understand how Peter came to the conclusion that "Claude" could help him control his powers. Other than that, I'm really enjoying the show.
Of the two children that we know have powers, both of their parents also had powers (Micah - DL & Nikki; Claire - Nathan & Meredith). I don't think we've run across any other Heroes who have had children with other heroes. Or maybe not -- you have Sanjog and we don't know anything about his parents. We don't know for sure about Molly and her parents. Her dad was scalped in typical Slyar fasion, while her mom was just killed with knives. Sylar pursued Molly into a dangerous situation, so I'm guessing he knows she has powers.
I'd really like to find out how Hana's (Wireless) and Micah's powers will interact, if at all.
More later.
