TL;DR Only timers for dialogues that you directly have with a companion are affected, others are not.

Not a bug, but something I just realized was that only the dialogues with exclamation marks that have the potential to affect attitude are the ones that have their timers increased, that is, the ones where you talk to a specific companion one-on-one.

I did not realize that the other dialogues with exclamations that do not affect attitude, such as the ones where the narrator says something, you share your thought and then all of your companions automatically share their own thoughts, were not increased.

Those dialogues are hard to miss though, since you only need to talk to any one of your companions for the whole sequence to be triggered and to hear the thoughts of all of them. In addition, these don't give you the opportunity to affect attitude with your companion and don't contain any plot or backstory.

I would like to increase those as well, but I cannot find what timers affects those. It has not been a problem for me in-game yet but it would be nice to do those as well.
