Whether or not Jason can hit his notes at VPOPS rehearsals is a real 50/50 coin flip, but when he's not fighting for his life trying to harmonize with everyone else you can find Jason waddling around on various side quests as he undergoes the trials and tribulations of adulthood.
Current side quest missions include: trying to lose the blob of belly fat he acquired whilst eating his way through London so he can look good at all of his friends' upcoming weddings (Jason's friends need to stop getting married... they're making him go broke), learning how to drive (again), mustering up the courage to sign up for a stand up comedy open mic, scoring a goal at pickup soccer, and figuring out how to stop being so anxious at social events with strangers (his brain keeps on finding new and creative ways to ignore his therapist's advice and exercises).
