Josh is about to launch a new app and hires a new assistant Randall (guest star Charlie Saxton), who is the epitome of efficiency and work ethic, to help him with this busy time. Thinking Randall is a little too good at his job and out to get theirs, Gabi, Elliot and Yolanda set out to get him fired. Meanwhile, Sofia is annoyed at her new neighbor (guest star Gregg Sulkin) for constantly playing loud music, until she meets him face-to-face.
