Castle’s daughter, eighteen-year-old Alexis, is his only child from his first marriage. Alexis is an old soul who is wise beyond her years and never ceases to amaze Castle with her wisdom and insight. She has inherited Castle’s charm and wit but rebelled against his devil-may-care attitude about life by being overly practical and methodical about her own. She’s honest and loyal to a fault (even in the face of peer pressure) and holds high standards for herself and those she loves.
Sometimes in her relationship with her father, it’s difficult to tell which one’s the parent and which one’s the child. But as she approaches adulthood, Alexis is beginning to challenge her relationship with Castle and isn’t afraid to test her limits. It’s the time in her life when she needs to figure out who she is and what she wants, even if Castle isn’t on the same page. However, she knows that no matter what, whether she fails or succeeds - he will always be there to cheer her on.
As early as she can remember, Molly Quinn has been a part of the performing arts. Early ballet recitals and continuous stage productions from K-3 through 6th grade set the stage for performing in front of the camera by age 12.
Quinn recently starred in the Newline Cinema film, "We're the Millers," directed by Rawson Thurber and also starring Jennifer Aniston, Jason Sudeikis and Emma Roberts. Prior to that, she played the starring role in "Hansel and Gretel Get Baked" from director Duane Journey and producer Mark Morgan ("Twilight" series, "Percy Jackson & The Olympians: The Lightning Thief").
Quinn's past credits include working alongside Renée Zellweger and Logan Lerman in "My One and Only," and with John C. Reilly in "Walk Hard: The Dewey Cox Story," directed by Jake Kasdan for Sony. She also worked for acclaimed director Robert Zemeckis in the motion-capture version of the Charles Dickens classic, "A Christmas Carol."
When Quinn's not in front of the camera, she works on numerous projects as a voice-over artist. Most recently cast as the voice of Supergirl for Warner Bros. Animation and DC Comics, she has voiced roles for Cartoon Network's hit series "Ben 10: Ultimate Alien," and is currently the voice of Bloom in the Nickelodeon global hit, "The Winx Club." She also narrates and brings to life each character in the audio-books for Simon & Schuster's YA series, The Mortal Instruments, by Cassandra Claire.
Currently residing in Southern California, Quinn stays close to her roots by regularly traveling home to visit family and friends in Texas.
