Queries :: Match Multiple Rows From Same Column

I have parent-child one to many data in one pair of relationships, and now I've been asked to see be able to find out what matches a defined regimen; each is also defined in a parent-child relationship.

Best is to show sample data. I'm going to show them as two tables, but the "Components" are actually in a parent-child relationship, e.g.,

PersonList -= Meds
Regimen -= Meds as well

Note that PersonList and Regimen do not really have any relation; we just want to see if things are being done one of the ways they are "supposed" to be done, without a slow manual check. It's worked as set up for reports, and I really don't want to change everything to a big long list of fields, one field per med for a lot of reasons (not least of which is that is denormalizing)

Quy 1 Result:
PersList T1Component
Andrew Med 1
Andrew Med 2
Brett Med 1
Brett Med 3
Brett Med 4
Charles Med 2
Duane Med 1
Duane Med 4

Quy 2 Result
Regimen T2Component
Goody1 Med 1
Goody1 Med 3
Goody1 Med 4
Goody2 Med 1
Goody2 Med 2

I'd like to be able to do two queries - one that are "OK" one that are not. Don't need to replicate the med list, just the regimen if matching..

"Good" would return
Person Regimen
Andrew Goody2 (he has med 1, 3, and 4)
Brett Goody1 (he has med 1 and 2)

"Bad" would return
Person
Charles
Duane

What they "almost match" does not matter; it tells people which ones we need to check into a bit more.
