No doubt a coincidence but answers like 10a, 24a, and 19d do seem to be 'of a kind', while 12a hints at the consequences or lack thereof.
I've decided I'm not happy with my parsing of 13a. If I'm coorect, it's 3,2,3 around "lead to mortifying" - but, if that's right, how is the meaning of 3,2,3 any different to 3,3 and are either really defined by "backgound" - assuming "checks" is a containment indicator?
