Wherein Joat has a howling good time.
Yes, "part," rather than "day." Here is where the time-skips start coming in, and the game is not clear how much time passes with each skip. I considered making this "Day 19+X", adding a new variable for each time-skip, but I imagine that joke would get old rather quickly, as well as confusing to newcomers.
Also, the next part is heavily implied to take place on the same day, so there's another reason to go with "part" instead.
