Heroes: Halp!

So, the third season finale was pretty good. This season seems a lot more promising than last. But I've got one question: did ANYONE follow the Peter Patrelli story line? Future Peter's consciousness is in Weevil's body? Or is that present-Peter's? But, the scar-face-Peter guy seems to still be Peter too -- caring about Claire and his brother and not doing anything so maleficent so as to make HRG affraid to even describe his evils to Claire. Did I miss something? Are there two Peters running around in present day? Where is the evil Weevil guy's consciousness hidden? I am so confused.
