At a birthday, Lenka urges guests to drink sparkling wine, and someone spots effervescent tablets added to the glass. A guest from the countryside refuses, saying they’re not used to fizzy water; Yasin offers to drink it for his wife. Moments later, after a shocked "No!" and a hurried "Yasin!", a guest says, "It's so hot. I feel dizzy." Others rush to carry them to a bedroom as the celebration unravels. The episode ends with someone calling "Hey, Zoey!", leaving the cause of the collapse and who will answer unresolved.
