Check a Side quest's reason names the Regular its citation resolved to

The reason check compared normalized names, so a reason naming only
"Beef Chili" passed for a citation of "Easy Beef Chili". Find the
Regulars the reason names with the same find the citations use, taking
the longest run of words at each point, and require a cited Regular
among them.
