5. Walter, Peter & Olivia
The three core characters of Fringe all began as lost souls. Walter was in St Claires hospital, Peter getting involved in things he shouldnt, and Olivia had been working for Internal Affairs. After grouping together weve seen them develop over the years, with Peter always being the linchpin of their emotional stability throughout (even when he didnt even exist). Walters always battled with/ tried to make up for his guilt over what he did, while Olivias been constantly searching for answers about what she was, and what shes become. The past two seasons have seen these relationships severely torn apart by Peters deletion, and then the Observer invasion- and if one things for sure, weve surely got more pain to go through first before the resolution.
The Questions: Will Walter resolve his guilt? Was Walter even responsible for the deterioration of the Universe? Will Peter and Olivia be able to settle down after things? Will they get Henrietta back? Why was Olivia special? What happened to Olivias sister and niece? Does Peter still have a son in the alternate Universe? Who was Mr. X?
