3rd of the first CG for Julian needs a Julian win at the dice game (probably with a decently high relationship with him. Can't quite remember off of the top of my head without looking right now)
second pictue for Julian is a bit more involved. There area few ways to get it, but the easiest one is probably have a high relation to Julian, then win the dice game and ask Julian about below his waist. That should open up a scene with him in the evening of day2.
