As someone commented above, damn we made Layla cry (again) if you broke up with her at camp. I must say I loved Layla's first time having sex. That's one of the more (if not the most) realistic ones I've seen in an AVN/porn game, especially with regards to Layla's behavior. I already predicted it when I saw her all overly dressed up, the MC noticing her nervousness, her buying multiple drinks without getting too drunk and the different looks in her eyes. It was a sweet first time.
Regarding Gabi's friend, I'm with you. I'm guessing she is Val's mom. And she might be the Entangled actress. Val is quite secretive and private. I wouldn't be surprised.
Also I noticed, perfume advertising guy client actually appears in an earlier scene as foreshadowing.
