EDIT: But what happens if a companion triggers a cut scene and it is a really important story moment, and you happen have your companion selected at the time for dialogue?
I think important story conversations default to your main character. You can control party members in some conversations with other NPCs and events around the world so you could have Wyll talk to other NPCs for your and whatnot. Just not with other party members and in key story moments. Like when you to interact with an NPC who asks you to sacrifice a party member, I don't think anyone but your main character can be in control of that conversation even if you approach while controlling one of your companions.
