Was wondering how you had B as first letter of 1a and 1d - they can't intersect with anything else?

[eanceoil]

If poorclare is like me, she probably put Brilliant for 1 down first, that left me stuck all day

[fiction-factory]

Isn't brilliant in the clue though?

[eanceoil]

I never seen brilliant in the clue, silly me

[poorclare]

Captain my brain just does not work, for some reason I was thinking Beautiful
as 01d, I am really struggling with this one, am going to give it a rest for awhile, am taking myself for a walk.
Thank you and Scorpiojo.
