Coming back to this thread, I was at the end of act 1 and ran into something interesting and stupid. Before swapping over to the new act wanted to test to see if I would get additional cinematics if I spammed long rests. I actually came across multiple different dialogs. One possible important one and the rest is just companion dialogs.

Going to use spoiler tag for them, along with a funny side note related to one of the dialogs.

I didn't get the dog until the very end when doing my wrap up (walk around), so all the dog dialogs came spewing out.
Guardian cinematics, I didn't get any till end and one of them was related to moving into the next area (this was the one I'm figuring I would have missed, didn't test though).
Fight between Shadowheart and Lae'zel and possibly Lae'zel trying to kill me (its been about a week since I did my wrap up and forgot to post my findings, so going by one save and memory).

The side note: if you ignore the fight between Shadowheart and Lae'zel, Lae'zel will die and she will be thrown where her tent was with just a grinder. Thought this was funny like someone packed up her tent and just left her their.
