I pulled out 42A Small bouquet: POSY because that’s the name of the rabbi whose class I attend via zoom most Thursdays. It’s a class that’s about what’s in the bible and how it applies today rather than just what’s in there the end.
15A Flummox: BEWILDER.
17A Flummox: BEMUSE.
55A Flummox: BEFUDDLE.
52A Flummox … or a classic word game represented by the central grid of shaded squares, in which 15-, 17- and 55-Across can be found: BOGGLE.
The puzzle online animates the four theme clues as they would be in the game Boggle one letter at a time. It’s way more decent a theme than I had expected.
Finished this one in 24:33.
