Also, there was a toggleable option to make surprise dialogues default to Tav since launch, it just was never fully conssitent.
You know, I've played this game from the beginning of early access, and I can't remember this toggle. Although you're the second person to mention it recently.
It must have been there, and I must have missed it.
I recall back in the day there were tons of people begging to make Tav the default speaker. Folks were getting upset that companions were sort of stealing the spotlight, so to speak.
