If there's anyone who can relate to the idea of waiting for your soulmate, it's Luke Danes. He stays patient year after year while the woman he loves dates one guy after another. Luke himself has some relationships along the way, too, though they never last too long.
That's why his big speech to Lorelai in the final episode of the revival is so significant, because it calls back to Luke's whole experience over the years agonizing over whether he'd ever get to be with Lorelai. He calls back to Max, Christopher, even Nicole — he even admits how especially hard it was to watch Lorelai marry Chris and face the possibility that he might have lost her forever. It's an unusually emotional scene for Luke, and it reminds the audience of just how far these two have come.
