Understanding 「あの後のオヤジとあれからどうだった？」


From the second episode of Death Note, a classroom a student says to another
student:

> って **あの後のオヤジと** あれからどうだった？

  1. I'm curious about this `<NOUN>と...<COPULA>` usage here. Is this slang for something else, or is it considered grammatical? Is と just the particle meaning "with", in this context?
  2. あの後のオヤジ means "afterward's old man"? I assume it means something like "the old man (placed in time after something just happened)"?

Is a good translation something like

> After that thing happened (あれの後), what happened with (と) the old man?




> あの後のオヤジとあれからどうだった？  
>  How was it with the old man after that?

  1. Yes it's と meaning "(together) with". But note that "what happened with ～" does not necessarily carry the meaning of this と, especially when it marks an event or situation. A more explicit translation would be "What happened between you and the old man?"
    * 彼に何があったの?  
What happened to him?

    * 彼と何があったの?  
What happened between you and him?

  2. Yes, あの後のオヤジ is a noun phrase, "the old man after that". Another similar examples would be: 
    * 当時の私  
the me back then

    * 将来のあなた  
the future you

    * 10歳のときの彼女  
her when she was 10
