Relative finds Ned conscious after smash (6,6)
I believe the answer is:
second cousin
'relative' is the definition.
(second cousin is a kind of relative)
'ned conscious after smash' is the wordplay.
'after' is a charade indicator (letters next to each other).
'smash' indicates anagramming the letters.
'ned'+'conscious'='nedconscious'
'nedconscious' with letters rearranged gives 'SECOND COUSIN'.
'finds' is the link.
(Other definitions for second cousin that I've seen before include "Some family" , "Relative" , "Fairly distant relation" .)
