Tonight; I liked how we got to see Hiro encounter his past self and tell him to rescue Charlie 6 months in the past because it was his new mission. He told him this because he realized that just sending Sylar away was not going to let him travel back 6 months like he did before.

lol, yeah! Those who says Hiro's bad now, they gotta rewatch this episode! He've put everything perfectly together so that the only thing changed is Charlie being saved:

1- Save Charlie
2- Since Charlie is saved, lie to past-Hiro that he has to time-travel, so that he indeed does time-travel (loved the ''moron'', and the Crono/Marle reference! )
3- Since Hiro didn't disappeared in front of Ando, warn Ando that past-Hiro time-traveled and he has to wait for him!

Perfect! I have to say, in this episode, Hiro was truly the master of space and time!

I thought it was pretty funny when Hiro actully talked exactly like the other future Hero but also seemed to act excited sometimes to. lol

One thing is for certain: we're going to need a better way to distinguish all these different Hiros flitting back and forth than just pHiro and fHiro.

Well, this Fhiro can be KRHiro, since he's got the Knight Rider shirt...

I just want to know, if this is now the predestined future that P_Hiro is seeing ahead of him, when he jumps forward 5 years near the end of S1, does he now have a totally new adventure in a totally new future? Or does the 5YG future still appear in temporal bubble even though it is not destined to exist at all yet?

The problem with 5 futures having a root history to splinter off from... lol.

Time is relative, psychopathic! For sake of explanations, let's call them S4-Hiro (for season 4) and S1-Hiro (for season 1).

So if S4-Hiro went 2 years (?) into the future, right now, he'd probably see a future related to the mischiefs of the Carnival, or something similar. Anyway, the future that will happen if he doesn't solve the actual situations.

However, if S1-Hiro went 5 years into the future, he'd see the ''Five Years Gone'' future. because he'd see what the world will be if he doesn't change what happened in season 1. Because he is past-Hiro, not present-Hiro. He still have 3 years to live and influence the world!

I mean, relatively, for Past-Hiro, he is Present-Hiro, and Present-Hiro is Future-Hiro, right? That's just my point: For Past-Hiro, the New York Nuke problem isn't solved yet, that is, for him, the ''Five Years Gone'' future is still his future!

Whew! Where is Marty McFly and Doc Brown when you need them?

You guys are all forgetting that Charlie was removed from the time-stream so as to have a zero sum effect on events that happened after she died. Now, if she had been left in the past, THEN the future would be changed, possibly considerably. Currently the only thing that has changed in that town/past/current is that they will not be gossipping about Charlie dying, but wondering what she was doing after she left.

If you guys are going to try to discuss time travel and its possible effects, you need to think through all the ramifications.

This aspect of the show bothered me a little. They can't just stick Charlie in the past and not give her instructions like don't get pregnant, or try to just blend in, or become a nun. If they sent her into the future, that future may not exist in a few episodes and she'll be with Caitlin.

Yes, that's one of the problems. If he had taken her with him to his current timeline he could have avoided all of that. The problem is the carnival guy. He doesn't think about what his manipulations may do except for how it may impact him NOW. So when he saw a chance to blackmail Hiro into doing what he wanted he took it, regardless of what the consequences to someone he didn't care about (which is only himself since his brother is apparently dead).

Except that he also told Sylar that he was destined to kill a lot of people and then die alone. Assuming Sylar doesn't get Haitaned later, that's got to have some impact on what he does in the near future. (He's also learned that he can use his power to save lives as well as steal powers; that's an awareness he didn't have in the original timeline.)

as far as sylar being affected...

anyone wonder if that even matters? b/c if some things are just destined to happen, sylar has suffered many a brain scramble and/or identity crisis.

One thing about this episode that I didn't buy was when Hiro told his younger self to go back six months to try to save Charlie. Remember in season one Hiro hadn't learned to control his power yet. The only reason he ended up going back six months in the first place was because he over-shot his original goal of going back one day.

So now we're supposed to believe that he successfully went back to the time present Hiro told him to? Early Hiro just didn't have that degree of control.

His past self probably didn't go back immediately six months... he might have gone back six years, and then leaped forward to the right time eventually... we just don't know.

How do we know that he didn't? If he's had a time traveler among his crew, he likely has some understanding of the sensitivity needed. He also seemed to indicate an understanding of this when he was giving Hiro advice earlier in the episode. I don't think this is his first rodeo.

If he was smart, Samuel probably just traveled to a younger version of himself and given Charlie to himself to hold captive. Then he could maintain some control over what she does, and also his current self would know if something goes wrong (like if she escaped, or Hiro rescued her) because his current self would remember it.

On the contrary, it seemed that he did have this awareness, as he was the first to say he could fix things, and he had certainly used that power on watches. At the most, we can probably assume this was the first time he had a reason to fix anything else.
