Its called The Invisable Thread.
Yah I guess Peter could be the fake death, but it'd be lame since they already pulled that stunt on him in Volume 1. Unless he comes back as his bad ass Future self from Volume 1. Now its confirmed that Hiro is going to die. So both heroes sacrafice themselves some how, Peter will prob do it to kill Sylar while Hiro will prob do it to stop the explosion that's my guess. But it'd be freakin cool if they teamed up for the finale. But I am hoping Peter doesn't die at all.
