This is the 'Gilmore Girls' episode where Lorelai and Luke's relationship began

During the Gilmore Girls series finale, viewers watched Luke and Lorelai reunite with a passionate kiss. This was the moment many had been waiting for ever since the two broke off their engagement and Lorelai married (and later separated from) Rory's father, Christopher. 

Finally, with the release of the revival series Gilmore Girls: A Year in the Life on Netflix, fans will find out where Luke and Lorelai's relationship went after their season seven finale kiss. And if the promo photos for the new episodes tell us anything, it's that the two are very much so still together.

But, as with all of the relationships Lorelai has had, this one will not be complete without moments of self-doubt. 

"I thought I knew exactly what I wanted," she says in its first trailer. "But lately, I don't know, things seem hazier." While talking to her therapist, she adds almost hesitating, "We're happy. Luke and I are happy." 

So with this in mind, we decided to look back to the very first episode that Lorelai and Luke start their romantic relationship. Because, who knows, maybe this will hold the clues as to whether or not the two make it through the revival as a couple. 

Season four, episode 22, "Raincoats and Recipes"

In season four's finale, Luke and Lorelai share their first ever kiss complete with the adorable "what are you doing?" and "would you just stand still" banter. 

Luke was staying as a guest at the Dragonfly Inn as part of the test run. Their kiss almost didn't happen because Lorelai's ex-boyfriend Jason showed up and told Luke that the two were, in fact, still a couple. Nevertheless, Luke and Lorelai did get together and start their romantic relationship after this episode and throughout season five. 

However, true Gilmore Girls fans would know that, although this was technically when they started dating, the two had been flirting with one another ever since the first ever episode of the series. Below are a few throwback moments to when their chemistry was evident for all to witness. 

Season one, episode one, "Pilot" 

Though the flirting was definitely kept to a minimum, Luke and Lorelai share a moment towards the end of the episode when she tells him he looks nice and he returns the compliment. 

Season one, episode 12, "Double Date"

In this episode, Lorelai goes on a double date with Sookie, Jackson and his cousin Rune. The date ends at Luke's Diner where Lorelai and Luke play cards. He almost asks her out, saying "You know, maybe sometime we could ..." before Mrs. Kim barges in yelling. Later in the episode, he does ask Lorelai about hanging out, saying, "Maybe we could do it again sometime." 

Season one, episode 14, "That Damn Donna Reed" 

After Lorelai offers to help Luke paint his diner, the two end up under the diner's counter looking at something Luke's dad had written many years prior on the wall. Not only are the two physically together at this point, but they stare into one another's eyes and seem to be about to kiss before Taylor knocks on Luke's door.

Season one, episode 21, "Love, Daises, and Troubadours"

Throughout the beginning of the series, Luke is often seen visibly shaken while listening to Lorelai talk about the current man she had been dating. But it wasn't until he met Lorelai's boyfriend Max Medina face-to-face that his jealously became overtly apparent. Luke made sure to let Max know just how much he does for Lorelai.

"I just left my toolbox from when I was here earlier fixing things," he said. "I do a lot of little things around here for Lorelai." He then added, "I'll always be around."
