"Fringe star John Noble has revealed that the two versions of his character Walter will be forced to form an alliance. The actor plays both eccentric scientist Walter Bishop and his parallel universe counterpart Walternate on the Fox sci-fi drama. Noble told TV Guide: &amp;quot;We do have arguments with ourselves. Most people seem to have this conflict within themselves and it can be quite vicious.&amp;quot; However, Noble added that the rival Walters will eventually put aside their differences to prevent their two worlds unravelling. &amp;quot;[The Walters] will build...up [their rivalry] until such time as they realise they&amp;#039;re being childish,&amp;quot; he said. &amp;quot;They have to put this extraordinary brain into one piece to solve a problem larger than their own egos.&amp;quot; Noble recently announced that the original Walter will be rendered &amp;quot;quite insane, agoraphobic [and] obsessive compulsive&amp;quot; by the disappearance of his son Peter (Joshua Jackson). &amp;quot;[Walter] won&amp;#039;t leave the lab,&amp;quot; he previously confirmed. &amp;quot;He hears voices and has hallucinations [because] he&amp;#039;s crazy! He still can solve problems, but he has to get Astrid (Jasika Nicole) to go out with a special [camera] so he can see the crime scenes because he won&amp;#039;t go out himself.&amp;quot; Fringe will return to Fox on Friday, September 23 at 9/8c. &amp;gt; Fringe execs &amp;#039;know how show will end&amp;#039; Watch a video teaser for the fourth season of Fringe below:      "^^<http://www.w3.org/2001/XMLSchema#string>
