Waterdeep Dragon Heist: Session Zero!

Dave takes over GMing, and forces our heroes to try a new way of making up characters together! Jared's dutybound half-aquatic elf monk solves crimes for the city watch, and is a former rival of John's tiefling bardic scholar scoundrel, who grew up with Rob's hardass half-drow wizard, who is the illegitimate half-brother of Mikey's human noble paladin zealot, who employs Mike's aasimar rogue softie as a personal assistant, who shares the same tattoo as Jared's half-elf monk! Simple! Together, they fight crime! Or possibly other things!  Bonus segment: why is Mikey called 'The Situation' at home?
