Qui-Gon remembered the cups they had been offered by the priest upon arrival. One for him, one for Obi-Wan.
“Your priest has poisoned my apprentice?”
“Poisoned? No! Never. It is a symbol. A symbol to our deity that we have found a worthy gift for it to claim.”
“How does your deity claim this gift?”
“Oh, it calls to the anointed. It joins their energy to its own. It is a blessing to be so worthy.”
