Given that AB has correctly surmised who Q is, and AB's knowledge of Q is correct, circumstantial evidence that Q=V would be that Q re-establishes contact with his family and then they are all killed by V.

I currently believe that Q is V in some significant way, but they are not 'the same person' either.
