Once a member of the ABC family, always a member of the ABC family.
Before he was kicking ass and breaking hearts as mystery writer Rick Castle, actor Nathan Fillion was busy examining the ladies of Wisteria Lane. And when we say "examining," we mean that quite literally — his character, Dr. Adam Mayfair, was Desperate Housewives' resident OBGYN.
Nathan appeared in a total of 11 episodes, from 2007 – 2008, during the show's fourth season.
To help celebrate the show's eighth and final season, Nathan attended the series finale wrap party this past weekend, April 29, 2012 at the W Hollywood in Hollywood, Calif.
We're not used to seeing Castle's main man without a pretty little squeeze on his arm, but for this bittersweet occasion, Nathan was joined by his father, Bob Fillion.
We're glad the 41-year-old actor was able to take a break from filming Percy Jackson: Sea of Monsters to spend some time with his dear old dad.
Which reminds us … we still haven't met Rick Castle's dad. Maybe it's time for Bob to join the ABC family!
