Yvonne Strahovski, Tricia Helfer

It'll be geek-meets-geek nirvana when Chuck starts answering to Battlestar Galactica's Tricia Helfer. The blonde beauty has been booked for a guest-star gig as the walking Intersect's new handler, sources confirm for TVGuide.com.

As first reported by EW's Michael Ausiello, Helfer's CIA agent will be placed in charge of Chuck and thus work alongside Casey when General Beckman decides that Sarah might no longer be an effective handler, due to her increasingly apparent feelings for the "asset."

But fret not, Yvonne Strahovski fans. Cooler heads must ultimately prevail — that, or Helfer's CIA spook turns out to be, like, yet another deep-cover FULCRUM agent — seeing as the Galactica gal's gig is just for a single episode airing about two-thirds of the way into the season.
