Castle Flashback! Nathan Fillion and Molly Quinn at the Season 1 Wrap Party! (PHOTO)
It's hard to believe that it's been over three years sinceCastle first premiered back in March 2009. Now in its fourth season, ABC's hit crime procedural has become an integral part of our lives, one we couldn't imagine getting through a case of the Mondays without!
Unfortunately, the Castle screenwriter wasn't able to get a photo with Castle's resident mystery writer, Nathan Fillion, so she did the next best thing: She tweeted a picture from the Season 1 wrap party!
