I gave a list of all the results. Most roles do have a unique vist result (I need to add in spy's) But all but 5 of those only show under specific circumstances. Of the 5 that always appear none of them are killers.
For example the escort and consort only receive a result that this role cares about if the other target is SK. (you were killed by the sk you visited!). This means that if you suspect someone of being SK and you think you know an escort then you can confirm both suspicions at once. Otherwise you will rarely get anything from an escort/consort.
FYI if you target a mafioso then it will not display the GF message. It displays the message he gets for VISITING the target, it assumes nothing is stopping the visit attempt such as an roleblock or a control, the GF counts as this and is thus ignored. Either target being jailed however will stop the ability, and you get only 1 message per use of the ability so you would never see the "GF ordered you to attack his target" message.
