Which foursome scene? :D The one with Zady is connected to Grey and his events. It depends on how far you're with him and what choice you made. It's hard to say exactly what you need to do, without knowing what you've already done and how far you're with the connected characters. ^^"
The bar is at Havaria port, but the events that bring you there start in your castle. Where are you with Grey's events atm? What was his last event you had?
