Relatives I depicted in unpleasant scene (6)
I believe the answer is:
nieces
'relatives' is the definition.
(I know that niece is a type of relatives)
'i depicted in unpleasant scene' is the wordplay.
'depicted in' indicates putting letters inside.
'unpleasant' is an anagram indicator.
'scene' is an anagram of 'neces'.
'i' placed inside 'neces' is 'NIECES'.
(Other definitions for nieces that I've seen before include "Relatives of 27dn" , "Relations" , "They're family" , "They're related" , "Relative girls" .)
