The Star Trek actor plays William Bell on the Fox sci-fi drama, which has been renewed for 13 final episodes.  &amp;quot;It will depend on what they have in mind for the character,&amp;quot; he told SciFiNow. &amp;quot;There are a lot of issues that have to be dealt with, but we&amp;#039;ll be talking [about season five].&amp;quot; Nimoy also hinted that Bell - who last appeared in the show&amp;#039;s fourth season finale - could become increasingly unhinged. &amp;quot;William Bell... started as a very intelligent and rational character,&amp;quot; he said. &amp;quot;I think he&amp;#039;s still very, very intelligent, but I&amp;#039;m not quite so sure that he&amp;#039;s rational anymore.&amp;quot; Fringe will return to Fridays at 9/8c this fall on Fox. In the UK, the series airs on Sky1. &amp;gt; Anna Torv on Fringe end: &amp;#039;I&amp;#039;d be happy with heroic death&amp;#039; &amp;gt; Fringe exec on final season: &amp;#039;The future world will return&amp;#039; Watch a teaser trailer for the final season of Fringe below:      "^^<http://www.w3.org/2001/XMLSchema#string>
