This is a scene I would have liked to have seen - what has been agreed in terms of (not) talking about the work?

In s6e1's musical intro to the series, one of the early shots is Elizabeth arriving late and them just exchanging glances and the barest of smiles before she goes off, alone, upstairs.

So is it 'don't ask, don't tell', up to the point where there's something about Paige?
