To make sure she stood out from the 9 other actresses that the producers had called back, Castillo admitted that she "decided to have fun." Though the character does not have a lisp, or the uni-brow, the huge glasses and the not so neat hair remain.
Sabrina comes off very afraid at times, and usually cannot be honest about how she feels.
She truly cares about people." Castillo described the character as "considering, kind and loving." She has a mind of her own.
Apart from her feelings for Patrick, Sabrina's whole life is defined by following in her mother's footsteps and becoming a nurse.
Castillo began filming her scenes on August 31, 2012.
During the audition, the actresses started out getting "pretty" to do a fantasy scene in which the character admits her love for Patrick, and then transforming into a nerdy girl with glasses for the rest of the scene.
