Scene changed after sailor gets leave (7)
I believe the answer is:
absence
'leave' is the definition.
(thesaurus)
'scene changed after sailor' is the wordplay.
'changed' is an anagram indicator.
'after' is a charade indicator (letters next to each other).
'sailor' becomes 'ab' (abbreviation for able seaman).
'scene' with letters rearranged gives 'sence'.
'sence' after 'ab' is 'ABSENCE'.
'gets' acts as a link.
(Other definitions for absence that I've seen before include "It may make the heart grow fonder" , "''. . . . . . . makes the heart grow fonder'' (7)" , "Need" , "Want, lack" , "Lack - it makes the heart grow fonder" .)
