...but how did Peter get his power back? Last I remember he was powerless. And how did it come back as only having one power at a time from someone instead of absorbing their power for good like Syler?

In the last Chapter's finale, Peter had to inject himself with the final syringe of Sureah's formula to keep it from blowing up the building they were all in. It gave him his power back, but it doesn't work in the same way. ie. plot device so Peter's not all powerful anymore.

But what if Peter touches Sylar and gains the ability to absorb any power?

That's not really Sylar's power. He figures out how powers work.

I'm not so sure about that. Foster daddy Petrelli taught him to absorb powers without killing the last season or so. Sylar hasn't done that since but it doesn't mean he can't do it.

I think the extra special restriction on Peter is that he has to TOUCH the person to get the power.

I was just throwing that out there. If Sylar is still all powerful Peter must somehow regain all powerful to fight Sylar. If, indeed, that is where the story is going. I don't know. Just thinking out loud. The writers might have all the Heroes with their individual powers beat Sylar's omnipower. That is; if Sylar is truly the uber bad guy.

Trying to figure this show out can make my head hurt.

Now I never said Sylar had to kill, just that he figured out how powers work.

Peter could, conceivably, touch Sylar and either A.) gain all the powers Sylar has or B.) absorb Sylar's ability to figure out how powers work and use it to gain powers.

I'm not so sure the show is going in the direction of a Sylar/Peter showdown now. We seem to have everyone against the Hunter and Nathan and then a whole other show about Sylar and his quest to find his past. There's been no connection between the two other than the occasional attempt to capture Sylar by Nathan's goons.

We've already seen Peter with Sylar's powers and it was not good. Perhaps even if he could, he knows better than to try again.

Now, Vogs, surly you're not saying that's a plot already used on Heroes are you?

Didn't Peter say in the episode before last that he can only hold on to one power at a time now? So who ever the last person he touches is/was that's the power he has till he touches someone else.

So with that thinking, even if he touched Sylar, there is no saying he'd end up with Sylar's original power. Maybe he would end up with what ever power Sylar last used?

Good point, Amay...and yes, he can only hold onto one power at a time. Perhaps his power will evolve to the point where he can hang onto more, or something will happen to make his powers change.

Some how I think they've got to make him at least potentially as powerful as Sylar for balance.
