The next several episodes feature guest stars as superhero applicants and, later, villains. The first applicant, Graviator, was played by rising star Conner Marx, who brought a delightful awkwardness to the role. We've all been in the position of interviewing in a situation where the company is not well prepared, and that lack of preparation somehow reflects badly on the person who doesn't even work there. There is also a reference to being put on the spot and tested on one's skills (and being unprepared to do so).
This episode not only marks the change of location, but also of a shift-around in some crew positions, and a step up in production value.
