Dialog system

Does anyone knows how the dialog system in the game works? For example, In my play through when I’m talking with Lady Stephanie there are key moments that I need to choose a response about how the events of the attack unfolded. There are the choices, one with a small picture of a mouth and a set of numbers for Henry and Lady Stephanie, a heart inside a crown and two sword,

What does the symbols and numbers mean?

The crossed swords are intimidation, the bottom symbol (the mouth, is for speech). I believe the middle symbol has to do with reputation but I’m not entirely sure.

The numbers match your stats to theirs, for instance if you have 5 intimidation and they have one, intimidation is almost guaranteed to work.

Middle one is charisma, based on your gear mostly…
Also please not that just having higher stat doesn’t guarantee anything (we were told and learned hard way)
