@Niara - I continue to find the distance between our interpretations of Wyll and Gale entertaining. If you could see my face you would see an enormous smile.
Like @Flooter I trust Wyll. Not as much as I trust Lae'zel - who would absolutely cut off the head my toon if she thought she was about to transform or if she sincerely believed Vlaakith wanted her to do so.
I go back and forth - Wyll or Lae'zel? Lae'zel took our side *and our instruction* when speaking with her people and that counts for a great deal. Besides she's already been betrayed by the Gith once if she were to be attacked by Gith again her faith in her people might hit a crisis point.
On Wyll I give him lots of leeway because of the nature of his connection to Mizorra. From the art and Wyll's description it seems she's an Alu Fiend and his concern for her / romantic attraction to her is likely due to her infernal charm. Wyll is under her spell.
This comes out in the intimacy scene with Tav. At first Wyll can't perform but a charismatic Tav can persuade Wyll to ignore Mizora's charm and focus on her. That scene seems like something of a synecdoche for the rest of his story. Will Wyll be consumed by his failings -- his love of glory, his want for power, his willingness to abandon ethics in pursuit of a goal -- or will he become the hero he imagines himself to be? The romance scene tells us that if Tav believes in him enough the lazy gloryhound can actually become the blade of frontiers.
I trust Wyll because failings come across as a tension and he's demonstrated an ability to break in the direction of goodness. He's not a good person but he wants to be one.
I rarely diagree with @Sozz and they're right once again. I'm not certain what we have to do to ensure that SH will side with the party and not with the Sharans come a crisis point. I suspect it depend upon how many memories we've recovered. My guess is that class ledger will be important because her name will be the key to unlocking her memory. And Larian just likes to do this - make a seemingly unimportant item incredibly important. I remember discovering power of tea in DOS2 . . .
Edit: Forgot to say, @Niara that your observations about Astarian were spot on.
