This family gathering occurs during the Christmas season, and is stated at time stamp 3:42 to take place 256 weeks before The Bear is set to open. That works out to 4 years 11 months. The Bear restaurant opens in May 2023, so 4 years 11 months prior would have been June 2018, obviously not during the Christmas season. Assuming this occurs in December 2018, it should have said something like "226 WEEKS TO OPEN".
In the kitchen while cooking dinner, Donna thinks Natalie looks sick and yells at Michael to get her some Brio-shee, referring to an Italian lemon flavored antacid similar to Alka Seltzer. A family as Italian as the Berzattos would never pronounce Brioschi as "brio-shee." It is pronounced "brio-ski."
When The car is driven into the house, no air bag was deployed.
Houses in these older neighborhoods generally have steps leading up to enter and exit the house (viewers see these steps when the siblings vent to each other outside). When the car was driven into the house, it should appear much lower and not directly onto the living room floor of the next room.
