Consider yourselves warned, Peter, Olivia and all Fringe fans: They are coming.

So teases a pair of new Fringe Season 5 promos, the first of which simply depicts The Observes walking toward the foreground, as foreboding narration is heard in relation to these individuals.

But the second trailer is what really has fans buzzing: it's in anticipation of the September 28 premiere ("Transilience Thought Unifier Model-11") and it teases Peter and Olivia (note her wedding ring) enjoying a beautiful day in the park with their daughter.

Until The Observers show up. Considering what we know about the year 2036, it's safe to assume this picnic won't end well. Watch and get extra excited for the return of Fringe now:
