In fact he expected you before (4)
I believe the answer is:
'you before' is the definition.
(I've seen this in another clue)
'in fact he expected' is the wordplay.
'in' indicates the answer is hidden within the clue.
'THEE' can be found hidden inside 'fact he expected'.
(Other definitions for thee that I've seen before include "Old objective second person singular", "Archaic form of 'you'", "Poetically you", "You (arch.)", "you many years ago".)
