As a part of his likes and dislikes, Cole (played by Matt Bennett), mentions his love of puppetry. Matt's character on Victorious (the show where he and Elizabeth Gillies met), Robbie, was famous for always carrying around and being insulted by his ventriloquist dummy, Rex.
Cole is played by long-time friend of Elizabeth Gillies, Matt Bennett. Elizabeth, Matt, and their other close friend Ariana Grande, met while working on the Nickelodeon show Victorious.
