Fox has released its official press release for the second season of Fringe.

Following the shocking May finale - in which Olivia’s anticipated introduction to William Bell revealed the existence of a parallel universe - the network hypes season two as follows:

Each episode of the sophomore season promises to uncover more about the larger threat and while some questions will be answered, new ones will surface. The intensity accelerates as Season Two opens with Olivia’s shocking return to this reality, and a determined Peter, unknowingly in a race against time with an ominous mobile force, pursues information about Olivia’s blurred and perplexing visit to the alternate reality.

Meanwhile, Walter reenters the lab to cook up a bit of fringe science, and of course, some custard for someone’s birthday.

Fringe is moving to Thursdays this fall. It premieres at 9 p.m. on September 17.
