If you cancel on the cosplay date with Lexi because of Val or Gabi, you don't get to go to the beach with Iris, Erynn and Lexi. You don't see Val with Tori, Darryl and friends.
But you do get the full Val park positive scene (kissing, licking, chasing around), and no more Lexi ultimatum.
And in your phone call with Lexi while she's with Layla on the way to the airport, it's weird that the MC gas lights Lexi that she's the one avoiding him.
So you can stall the Lexi-Val circles crossing for one more update at least
