Fringe star Jasika Nicole has revealed details about an upcoming storyline on the show.
The actress told the New York Post that viewers will soon see characters from the alternate world cross over into the regular universe.
"You're going to start seeing [them] in our universe for the first time," she explained. "We've seen it the other way, but it's going to start happening [that] way around pretty soon. It's limitless. I'm assuming if there are two worlds, [then] there are an unlimited number of worlds."
She also speculated that the sci-fi drama may begin to explore time travel in more detail, following the recent revelation that the Observer (Michael Cerveris) is able to cross the time stream.
"What would it mean for someone to come back from the past who had passed away?" she asked. "It makes me think that [issue] might be coming up in future shows, but I don't know for sure."
Fringe continues on Fridays at 9/8c on Fox.
