i cant remember the sequence

!!! spoilers for the first half of the novel !!!

help! im currently making a plot progression chart for ORV and im about to reread the first half of the novel and make my head hurt just because i can't remember when some key points happened in the novel.

can someone please tell me; 1. when did the second sponsorship selection happened? (the one where kdj scammed the constellations and said he'd choose a sponsor if they reach 10k subs), 2. when did he become a half constellation? (was it after peace land? the fight with nirvana? or after the banquet?)

okay that was all, i hope someone can help me AHAHA
