Was able to solve all clues except for 2D, which yesterday was nothing but the uncapitalized, italicized, and boldfaced word
entirely
.
Came back this morning to see it if made any more sense, and now it reads like so, including the quotation marks:
"Animal star sign." "Chameleon?" "Not entirely."
Now it makes perfect sense.
(But how is it possible that nobody checked it before it was foisted on solvers?)
