I'm not the world's biggest Nicole Richie fan, but even I have to admit that Lionel's tabloid-friendly offspring kicked some serious ass when she guest-starred on Chuck two years ago. So it's with great excitement that I report (exclusively!) that the sometime actress will reprise her role as Sarah's high school nemesis this fall!
According to a Chuck insider, Richie will resurface in October when a prison transfer goes awry and her character, Heather Chandler, ends up being stowed away at Castle (a.k.a. the underground CIA base). But here's where things get really interesting: I'm told her arrival dovetails with some serious bumps in Chuck and Sarah's deepening relationship. And you better believe that Ms. Heather will use that rift to her advantage.
Wait, there's more! Heather isn't the only legendary Chuck baddie to appear in this particular episode. Click over to Ask Ausiello to learn the identity of the other evildoer. And then come back here and fill up the comments section with your thoughts!
