P1: The party sits in silence until the rogue speaks up, "So... um... My parents are dead" 

P2: The gloom lifts as the rest of the party speaks up, "Same" says the warlock, "Really? Me too!" adds the alchemist, "Yeah mine died a while ago," Pallas offers. "Mine are dead too," The paladin says. 

P3: Vin hands Abby and Erry each a full glass, "One beer and one grape juice, on the house!" Off screen the party continues to chat. "How did they die?" "Fire." "Dragon." "Evil Wizard." "Pirates." "Theatre Accident."
