There will be some "fantastic" Luke and Lorelai scenes.
Talking with Us Weekly, Scott Patterson (Luke) confirmed that Luke and Lorelai will have some "fantastic" scenes together, including his favorite scene ever. "We did it in one of these four chapters. There are two that are penultimate Luke and Lorelai scenes. It will be the scenes to end all Luke and Lorelai scenes."
Patterson also spilled quite a bit about his relationship with Lorelai to E! News while attending Entertainment Weekly's pre-Emmys party in September:
"We are together and we are figuring out our next move. There are definitely some fireworks there. We did some really intense adult scenes. Since the movies are only an hour and a half long it has way more detail and the writing is deeper and seems longer so it sort of changed. Fans are not expecting this, but it's more a film now than it is a TV show. Also, Ed Herrmann passed away so we deal with that and that affects the whole dynamic. It affects all of the relationships. There has been sexual tension for a long time. We are together, and I mean we don't arm wrestle at night. It will be addressed again, and again, and again and then we have coffee . . . I'm going to get in so much trouble for this!"
