LORELAI: Thanks for doing this. I didn’t want the rain to destroy your beautiful chuppah. And I looked and looked in the yellow pages and I didn’t see a chuppah waterproofer listing anywhere.
Luke comes over because Lorelai is worried the chuppah Luke made for her wedding to Max might get damaged by rain – apparently this is the first time heavy rain has been expected since August? Or else there’s been so much successive rain that Lorelai is worried about its cumulative effect.
I’m not sure how Luke saved the chuppah from getting wet, possibly some sort of oil or coating to protect it from the elements (there’s a bottle of something in his bucket, but you can’t see the label). He also has to superglue the head of a wooden goat decorating the chuppah back on. It’s a nice symbol of how Luke is willing to maintain and protect his relationship with Lorelai.
As part of that, he asks Lorelai about her fight with Sookie, and listens to her fears about starting her own business, and her grief at losing her connection to the Independence. She speaks of the inn as her “memory home”, where both she and Rory took their first steps, saying it means more to her than her parents’ home (what a kick in the teeth for Emily and Richard!).
