2.16 - Aye, There's The Rub
From spiced at Fan Forum: there's an episode that they are either filming soon or writing at the moment where rory is home alone one night. dean wants to come over, but rory just wants to be alone. paris calls, wanting to study for some test. rory says okay. later, jess brings over food, supposedly a care package from luke (since lorelei is away with her mom). they all eat together, and when the meal is over, dean calls. rory says that paris is there, so he decides to come over. rory then pushes jess out the door, just as dean arrives. she lies and says that jess was just dropping off the food, but dean sees that the meal has been eaten. later on, rory thanks luke for the dinner, and luke says "what dinner?" anyway, this info is super-tentative, since the episode is only in the writing stages (i think). but this one comes after lost and found. all this will hopefully be confirmed in a few days to a week.
From spiced: paris and jess are going to meet in an upcoming ep, but no sparks will fly (the info is tentative, since they're not shooting that episode right now)
From mrsvw: The main storyline involves Emily and Lorelai going to a spa for two days and Rory is left at home alone. She doesn't want Dean to come over but Paris talks Rory into letting her come over to study chemistry. Jess comes over to bring food and ends up staying. He and Paris get into a literary conversation and then Dean shows up. Rory pushes Jess out the door. And she lies to Dean again, but Paris comes to her rescue!
From mrsvw: Rory and Dean have a make-out scene.
From spiced: dean and rory do have a great fight in "there's the rub" and she lies to him about why jess is there (well, paris claims it's because she had a thing for jess, and then later fills rory in on the fact that jess obviously likes her).

Although you say it wasn't the best ep, I still could kick myself that I missed it. 
Thanks again!
