Thanks Hal2003, I forgot about intuition. But it would really help us know that the skill is being used if they coloured the additional choice differently, like the dialog choices in the game Vampire: The Masquerade - Bloodlines. (In that game there are skills to charm and intimidate people: charm decisions are coloured pink and intimidation in dark blue, so you know what each dialog choice is supposed to do. It was quite a fun game.)
