Two stories about wine and categories of people: 1. A Jew sent to a non-Jew, on his festival, because he wasn't an idolater. But someone who hasn't converted might still be problematic. 2. Entering a bathhouse with a good number of prostitutes - with the fear of the monarchy or not? How to judge someone, and what if he's not who you think he is? Also, a new mishnah: wine that was used for a libation and skilled on grapes - when can you wash them off? Depending on the taste they give off - or not. Plus, a story to counter the apparent principle of the mishnah - leading into a general rule for application elsewhere. Plus, the Gemara re-writes the mishnah to correct it.
