For some, he is known as Nathan Petrelli in the once-famous Heroes. Now, Adrian Pasdar will be back as an FBI agent in the romantic dramedy Castle. In the TV series, a terrorist sends a message threatening to destroy New York, and the NYPD asks for help to the Department of Homeland Security. The FBI presents Agent Eric Fallon (played by Pasdar) who will appear in multiple episodes, including a two-part episode that will air on February 21 and 28. We say it’s actually a good choice since he portrayed Nathan Petrelli well in Heroes and we were already wondering when he’ll appear in TV next. Well, we can’t wait to see you Pasdar.
