Viewed the scene mentioned (4)
I believe the answer is:
seen
'viewed' is the definition.
(to view is to see)
'scene mentioned' is the wordplay.
'mentioned' indicates a 'sounds like' (homophone) clue.
'scene' sounds like 'SEEN'.
'the' acts as a link.
(Other definitions for seen that I've seen before include "watched" , "Espied" , "Observed or percieved" , "Distinguished" , "Spotted" .)
