Rory is the same age in this series as Lorelai was in season one of the original series.
Lane's father, Mr. Kim, was talked about in "Gilmore Girls", but never made an appearance, making him a mystery to the audience. He makes his first appearance in "Spring".
Paul Anka is again portrayed by the same dog actor named Sparky. He's a Polish Lowland Sheepdog and was 14 years old when the revival, A Year in the Life, hit Netflix
Lane is now living in Sookie's old house.
The very first "famous Gilmore Girls lines" the audience hears in the beginning of Winter, is the line "Please, Luke. Please, Please, Please..." which is where Lorelei is begging Luke for coffee. This line is the same very first line stated in the pilot episode of Gilmore Girls.
