Nathan and Susan will be hammock-reading neighbours too, along with Hermione. They need a club. ftw. Daphne will also move her laying out spot once in a while to come say hi to Nathan and so he can ogle her (she has no shame when it comes to this *facepalm*). She trusts him, anyway.
Ted is with George on the activities, but he's also taken it upon himself to set up refreshment on the beach! Lol. So when he's not busy having cookouts or attempting to mix drinks? Analisa would remind George about sunscreen, but apparently she's being antisocial. Sorry.
If Susan sees Jas on the beach, she will make him sit (lie? XD) with her in her hammock. Yup. Also she will suggest they come back later on at night when there are less people around because it's cooler and less people and pretty and stuff.
IDK if any of mine will interact with Wendelin or Theo, except maybe if Susan comes back to the beach at night, but she won't bother him if he doesn't want to be bothered.
