So, getting Alice to appear on thursday is a task that requires getting the right dialogue options in Xenon's route starting on tuesday. And I just got all achievements, the remove krypto and nothing happens on thursdays were the last two. I was right in assuming that it the thursday one required removing krytpo, so I assumed it was something that had to happen before that day, when infact its a weird thing that happens on friday. It also unlocked tons of optional dialogue that I spent probably about 2 hours reading (Because I didn't sleep at all last night and was nodding out while reading), but yeah. Just glad I got everything after 11 hours of gameplay, I'm dead inside (mostly because I stayed up the entire night playing this)
So, choose the dialogue option to make Jackie come back on thursday, then make talking to others a priority first, make her wait before talking to her, but wait too long and she'll leave. That should help you out. I'm not sure how much I'm allowed to spoil here and I doubt Eevee would like it if I just straightout gave all the answers
