Did anyone confirm fPeters death? Last I remember he was just lying on a table but still alive.
What if fpeter is still around? Assuming that Dad stole pPeter's original "absorption" ability (since he killed Adam by taking the ability he was born with), could fPeter come in and help pPeter regain all of his abilities by better understanding his original power? Sort of like Sylar teaching him the IA by helping him fix the watch.
Or maybe it really is as simple as Peter gaining access to the formula. but then would he be given a new power by this formula, or are we pre-destined to have certain powers by our original DNA structure?
