Plot Hole ??? I’m not even sure what that means….

Something during this rewatch is really bothering me. Did Paris not meet Luke at the diner in an earlier season with Rory? They were doing some sort of article or report. ? Then ffwd to season 5 when Lorelai ‘ Rory gave their falling out and Paris shows up at the house when Luke is there. Don’t they already know each other?!

I just thought maybe this can be blamed on the show runner change at the end of the show
