Yeah I haven't seen much indicating it would be a Mallory-centric update. I would be so hyped about more Mallory, but based on what they said in the livestream and the most recent update it sounds like it will be more story focused than anything with the sexy stuff being more with the side girls than the main girls. The chapter is called "Cause and Effect" so I'm guessing there will be an element of temptation with the side girls (
and the consequences that come with that) now that Alex has had a choice to lock in a relationship with both of the main girls. That said, I'm sure there will probably
some stuff with Mallory in CH7, but it will probably be limited to flirting.
Devs mentioned that the Moratorium on character deaths has been lifted, that there will be 2 bad ends, and one character is permanently leaving the story... My money is on one of two possibilities. Either George is getting whacked, or someone was dumb enough to steal one of his oatmeal creampies.
People do get lost at sea all the time
As far as the crossover, I doubt it will be Eternum. There won't' be any Eternum characters showing up in Chasing Sunsets or vise versa simply because it's Daz vs HS2. It's too different of an art style. They could do minor references like a logo show up somewhere or something, but I doubt SFS would bother mentioning it if the reference was that minor. I agree that Artemis is probably a big possibility, but my longshot hope is Elsa from
Corporate Culture.
