The Gemara picks up on Beit Hillel’s leniency from the previous day’s mishnah, and Rabbi Akiva’s opinion on “the gazelle and the hart” – which are permitted to a non-Jew to eat. And how that phrasing drives the interpretation, including explanations by Rishonim (the medieval commentators). Plus, the question whether menstruant woman could participate in such a meal. Also, a new mishnah! You can’t actively intentionally make a blemish in an animal, but certain actions that might leave a blemish are allowed to prevent a more lasting blemish. Note the shift to issues of impurity and purity, in the case of wine where there’s uncertainty as to whether it’s impure.
