Watched new episode, missing nothing (6)
I believe the answer is:
espied
'watched' is the definition.
(I've seen this before)
'new episode missing nothing' is the wordplay.
'new' is an anagram indicator.
'missing' is a deletion indicator.
'nothing' becomes 'o' (looks like zero - 0).
'episode' with 'o' taken out is 'episde'.
'episde' anagrammed gives 'ESPIED'.
(Other definitions for espied that I've seen before include "Spotted; saw" , "Glimpsed" , "Caught sight of (archaic)" , "Watched" , "Caught sight of (poetic)" .)
