When can I get Adria's conversations for the Bewitched achievement?

The achievement says to "Listen to all of Adria's conversations."

In order to not miss any, I'd like to know when Adria's conversations become available and if and when they become unavailable.

Solution 1:

I did a run through with a new character, noting when each of the conversations became available. This was compiled by listening to each conversation as soon as they became available. Some of these conversations are only available after having heard previous conversations and the specific dependencies are as of yet undetermined.

Adria stops talking to you after you start Heart of Sin in act III and by then any conversations not heard have certainly been missed.
