Became aware of episode involving tense director (7)
I believe the answer is:
scented
'became aware of' is the definition.
(scent can mean to become aware of something)
'episode involving tense director' is the wordplay.
'episode' becomes 'scene' (I've seen this in another clue).
'involving' means one lot of letters goes inside another.
'tense' becomes 't' (grammatical abbreviation).
'director' becomes 'd' (abbreviation eg in film reviews).
'scene' enclosing 't' is 'scente'.
'scente'+'d'='SCENTED'
(Other definitions for scented that I've seen before include "Sweet-smelling" , "Perfumed" , "smelled a rat, perhaps?" , "Having pleasant smell" , "Fragrant" .)
