here we seem to have a F/H weirdness
and there's another one just nearby
at the intersection of 11d and 29a
where the across clue wants to have F and the down one want to have H
they're not the same kind of thing
(one involves two clues we think we've solved that have conflicting answers and the other involves one clue that seems like it conflicting parts)
but it's a curious coincidence at least
and Deusovi's reaction to my saying "oh" at this juncture is interesting, too :-)
I wonder if there's an I/S swap somewhere too
the pattern of clue names is taken from a Dr Seuss book
but its full name is "one fish two fish red fish blue fish"
and given the fish-shape maybe there's some further fish-swappery going on somehow
I'm just babbling here -- I don't have a concrete clearly-statable theory for what's going on -- but something in this vicinity seems likely
look at that part of the grid, if you have been filling it in somewhere
middle row of the whole thing
