Eventually done wrong? Yes! (3,3)
I believe the answer is:
one day
'eventually' is the definition.
(I've seen this before)
'done wrong? yes' is the wordplay.
'wrong?' is an anagram indicator (I've seen 'wronged' mean this).
'yes' becomes 'ay'.
'done' with letters rearranged gives 'oned'.
'oned'+'ay'='ONE-DAY'
(Other definitions for one day that I've seen before include "#Eventually" , "sometime" , "In time to come" .)
