Question, in case I have missed something: have there been more changes other than polished expressions during the epilogue and Tav's face?
A few smaller things have been changed, such as how he responds to companions' questions when they ask about the relationship between him and Tav.
Ahh, okay, I'm assuming you're talking about the previously bugged party banter? I actually, personally, -from an opposing point of view- really like the insight you get from one of his interactions with Lae'zel. I fear I'm getting too off-topic, but I'm overtaken by my need to gush over that kind of stuff. My bad, I promise to stop now!
