Girl Meets World takes another walk down Boy Meets World memory lane in the show's latest episode, but it's not the fondest memory in Cory (Ben Savage) and Topanga's (Danielle Fishel) history.

In E! News' exclusive sneak peek at the first half of the two-parter episode, "Girl Meets Ski Lodge," airing Friday, July 22 and 29, you can see Mr. Matthews try to prepare his class for their upcoming field trip to the very same ski lodge that was home to one of his and Topanga's worst moments.

"The ski lodge was almost the end of Cory and Topanga, America's sweethearts, and now I know something's going to happen there for you, so I'm preparing ya. For nature," he explains.

As you'll recall, while on his senior ski trip to Mount Sun Lodge, Cory ended up having a very deep connection with Lauren, an employee there (played by Linda Cardellini). It culminated in a kiss and romantic letter—all instigated by Lauren, but not turned down by Cory.
