Pay a second visit, eh? (4,5)
I believe the answer is:
come again
I believe this clue is a double definition.
'pay a second visit' is the first definition.
'eh?' is the second definition.
(I've seen this before)
(Other definitions for come again that I've seen before include "You're welcome to return - pardon?" , "I don't understand that" , "Recall" , "return invitation" , "I'm sorry?" .)
