You know I'm not that much of a type of speculator (especially regarding something that is still in development, things might always be changed and rewritten any second). But what's the harm in playing along a bit, if you let me to. Anyway, I don't think it's about the beach date with Erynn. I mean, I'm kind of sure Nyx would not kill the whole DATE vibe by letting something like that to happen when it comes to finally having something romantically big with Erynn. Not on this particular date, at least. If it's still connected with Erynn and based on a choice previously made in the game (whether the MC sticks to the plan or beats the shit out of Ethan and takes his phone), it might be Ethan's phone and the MC wanting us players to watch the videotape. And here's an option to skip watching it, if you are too fragile and sensitive about such things. I know I may be pretty bad at speculating, but that's something I can only think of now.
