Processing on the events of Seder night: cup #2. The mishnah interpolates the child asking Mah Nishtanah with the manner of asking found among the 4 sons. To be asked by anyone and everyone who can ask. Note the "5th" question on the meat of the Korban Pesach! Plus, the versions of the story of the exodus from Egypt that is to begin with the Israelites' historical disgrace, and concluding with praise, with both Rav's and Shmuel's take on which texts should be here. And, of course, also the 4 verses from "Arami oved avi." Note also the "modern" approach of the Seder, in terms of the appreciation for each personal imprint. Plus: Rabban Gamliel's implementation of that telling of the Pesach story in the halakhot that pertain to the Seder: Pesach, Matzah, Maror. And Hallel. And concluding Magid. Also, what about those who are missing any one of the senses that pertain to the fulfillment of a mitzvah? For example, those who are blind. What happened in the homes if the sages who themselves were blind?! Is the talking enough, or must there be a visual component? (Spoiler: It's the speaking part that matters; the visual elements are to be integrated into the narrative).
