Three views about to be one (3,3,2,3)
I believe the answer is:
see eye to eye
'be one' is the definition.
'three views about to' is the wordplay.
I cannot really see how this works, but
'to' is within the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for see eye to eye that I've seen before include "Agree with someone" , "Concur; in accord" , "Speak the same lingo" , "Think alike" .)
