I may be wrong with some answers
8d Set at odds. I have estranges(or estranged)
12d. Redolent(9) I have evocative. Hence the "i"
20d Be off (4)i had Scat.
All these are linked in
Sorry my mistake.
11a. Clue given twisted(7) I have tweaked in. So 12d starts with "e" if I am right. I feel like giving up on it at this stage but thanks for your patience.
