Yale knew that he couldn't prove anything, but since he knew that the Lizardman God Cult tried to poison Wyba, they had already set their fate.
The poison wasn't a lethal one as it was meant for torture but knowing about that fact didn't diminish Yale's anger in the slightest.
The chef apologized while serving something else to Wyba, which Yale confirmed that wasn't poisoned. The chef was doing his job very well as Wyba liked the new dish.
No more incidents happened in the dinner, and everyone treated the previous incident as just a problem of Wyba with spicy food.
The lizardmen offered a place to sleep to Yale's group, but although they accepted it, everyone entered the Storage Space as that was the safest place, so the place to sleep offered by the lizardmen just served as a cover.
Yale was the only one left, and he went out silently while sending his Spiritual Sense towards the place where the lizardman chief lived.
