Thanks Mack---I'll mull this over.
E3 is easy once you see it: Def: 1st word. Wordplay: last letters (`ultimately') of the following 4 words.
I may be wrong with my B4, so I won't do that one yet.
Really enjoyed this. Arguably (again) not a crossword, but most of the clues were sufficiently straightforward that by the time I got to the trickier ones I actually had some checked letters. So all in all a fun challenge!
But I can’t parse B6. Think I have the definition (five words), but the wordplay completely escapes me. Please would someone put me out of my misery?
