Dyanna needs to pee. That's why he pees in the slave's jar. Afterwards, Dyanna sits comfortably and smokes a cigarette! He also uses the slave's jar as an ashtray. The bottom and the ashes in the jar he peed into. This is how you can make a delicious little refreshment. When it's ready, call the slavet and let him cocktail! He swallows every drop, the ash and even his bottom!
