Hmm i feel there's a couple of opportunities in 0.30 dance scene for some extra story continuity, and to iron out some wrinkles:
* with Jessica, Ethan can potentially pick a line earlier while checking out the dance floor, how he'd only like to dance with her, and depending on relationship status, Jessica answers that she'd love to, but later. But when you do approach her later, neither of them remembers this exchange (if it happened)
* with Samantha, there's this exchange about letting her lead in the dance, and again neither she nor Ethan have any memory that it's something that has already potentially happened during the dance all way back on Day 5, where --if you opted to dance with her-- you could've let her lead, or chosen to stick to traditional arrangement.
* with Luke, similar to Samantha, neither he nor Ethan have any memory they've potentially already danced together on Day 5, which can kind of make his incredulity at being asked and the whole having to convince him thing a bit out of place.
* with Aurora, she thanks Ethan after the dance:
"I've spent so long trying to keep this version of me locked away. The part that gets excited about silly magic tricks or slow dances or even talking to people who aren't ghosts," she admits. "But you made it feel okay. You didn't treat me like some creepy witch, even though you could've You didn't make it weird."
Which can feel really like an "oops" moment if the player has potentially picked to actually make fun of her for enjoying the magic show just short while back.
