I have no issue with the screenwriting and I understand the dialogs are unfinished. Yes this is the sequence after stepping into the hag's lair. Btw it is easy to reproduce. Incidentally I just got three additional opponents and two of them don't turn hostile if you talk to them after the fight. But it doesn't matter.

This just illustrates yet another issue with the dialog mechanics. This time not because this may trigger an unexpected (or rather illogical) series of events while one char is in dialog mode but because your "frozen" char is still impacted by the environment (and active effects).
