Really should be none…

I personally don’t support those list of what to say and not say on a date, I think any conversation could be started and stressed if you know effective communication, giving people list of what to say and some regarded as taboo would rather put them in a uncomfortable situation

you can choose to talk about your ex if you can pull it through another guy might not be successful with the same line of talks
what i am saying is that people can say whatever they want depending on situation and antecedents
