Despite her myriad of successes in planning for the Spring Gala, Katie is finally forced to follow-up on her promise to secure Nathan Fillion as the special guest. Aware of a nearby Fan Convention which he will be attending, she decides to take Oliver (who she gives a crash course in his cult sci-fi series Firefly). Meanwhile, Taylor wants to buy a prom dress for her junior prom, and though Trip was going to take her to NYC to buy the dress, since the convention is also in NYC, Katie insists that she take her instead.
