People die in a disgusting manner, the prison escapee Mr Jones shows up at the FBI, Olivia learns she is special, the IA prat is back and he seems unaware that one shouldn't provoke a lunatic. Also Loeb and Jones turn out to be followers of an anti-science self published manifesto/rant. And the author of this rant is none other than Walter. Though nobody knows this but him and he has apparently forgotten writing it. Also there are hints of multiple universes, a coming war and Mr Jones turning into something.
Questions remain: is Walter a goodie or a baddie and whatever happened to the hints that there is something preternatural about Peter? Anyway this was okish and seems to exist mainly to set up future plot arcs.
