Fringe star John Noble has revealed that his character Walter will struggle with insanity once again next season.
In the Fox sci-fi drama, Walter regained some of his faculties with help from son Peter (Joshua Jackson), but Peter was erased from history in the third season finale.
Noble explained: "Walter came out of that [psychiatric] hospital three seasons ago, and he was... pretty insane. [But if] he didn't have Peter to help him, he'd still be insane, so initially I think we'll see that."
He continued: "[Walter will] still work for Olivia and he'll still be brilliant, but he doesn't have that lovely softening element of a family."
However, Noble insisted that Peter will eventually return to restore the show's status quo, despite Joshua Jackson's recent claim that he had not returned to filming on Fringe.
"It's not going to last forever," Noble said. "We can't live without Josh Jackson!"
