Confirmed: episode 4.08 will be called Once Upon A Time In Texas.

4x01 : Orientation
4x02 : Jump, Push, Fall
4x03 : Acceptance
4x04 : Ink
4x05 : Hysterical Blindness
4x06 : Tabula Rasa
4x07 : Strange attractors
4x08 : Once Upon A time In Texas

I am especially intrigued by the title of 4X6,"Tabula Rosa".

Ep 8's title is most likely a referrence to Hiro and Charlie perhaps?

Wow, good call. Hadn't thought of that.

Awesome!
How many of them do you think they have finished filming?

They should be on 10 or at least nearly on 10 by now.

I think so too. I guess Hiro will always try to come back to his loved one. Remember the saying save the cheerleader save the world phrase? He did that for his love one Ando.. LOL

I loved Charlie! I wish she hadn't died.
I'm looking forward especially to ep 8. "once upon a time in texas" seems like a fairy tale. "Hysterical Blindness" should be good too. Sounds funny. I wonder who/what its referring to.

'Once Upon A Time In Texas' has to be a flashback episode probley about Hiro/Charlie... which somehow has to be connected to 'The Carnival'... I'm sure Nathan/Bio-Mom backstory is here too... It's hard to put all the peices of the puzzle together... but this is going to be the episode that moves the story arch foward and reveals something big or ties up some theories from the past...

On september third they had filmed up to 8 episodes so

Update:

4x01 : Orientation
4x02 : Jump, Push, Fall
4x03 : Ink
4x04 : Acceptance
4x05 : Hysterical Blindness
4x06 : Tabula Rasa
4x07 : Strange attractors
4x08 : Once Upon A time In Texas
4x09 : Shadow Boxing
4x10 : Brothers Keeper

im wondering what 'shadowboxing' could be about. a new ability maybe?

Well, apparently it's a Claire-centric episode, so...I have no idea

Shadowboxing - i guess Heroes wants to attract boxing fans as well since shadoboxing will be shown on the week of Pacquiao-Cotto fight.. haha.. just a guess.
