If an Israeli attends your 2nd Seder this year, when it's Motzaei Shabbat, how should he behave at your Seder table for the 1st cup of wine?
You will do a combo Kiddush / havdalah. He does no Kiddush but a regular M. Shabbat Havdalah. You and your family are the hosts and he is staying with you. What would be the best protocol?
option 1 - Listen to you make the entire Kiddush and you drink the wine. Then, you listen to him make the havdalah?
option 2 - "Share" the combo. He listens to you make the Kiddush (he will not say the beginning phrases "Hinei El".) He has to make Borei Minei Besamim so you let him. Both of you have to make Borei Me'orei Ha'esh, so he'll listen to you. He will listen to you make the rest of havdalah as the beginning words are identical to the weekday words; the ending is a bit "extra". The final bracha, while you say Ben Kodesh L'kodesh, he says "ben kodesh l'chol"
option 3- He listens to your Kiddush and Havdala and is yotzei through the words you said "Baruch ata Hashem.. Hamavdil Ben Kodesh Lechol..." even though the end of that brocho is "Hamavdil ben Kodesh lekodesh? This would apply to an American who made aliya and can't speak/read Hebrew yet. after Drinking kiddush anyone can make a brocho on Besamim for him.
