Thank you Ametris for coming to the rescue with the two cutscenes! Having seen Lae'zel's extended cutscene; now that's an amazingly badass 10/10 cliffhanger that fully respects her character motives, properly sets up her evil ambitions and sets up for the aftermath. Happy to have predicted it with the original post because that's exactly what she'd do. Naturally it's still a cliffhanger, but it's a truly badass one. My favorite of them all.
Karlach's on the other hand... dear Lolth preserve me, she received the same treatment as Wyll. Everything I said about Wyll stands for Karlach too. There's no evil story or character development here, this is just pure character butchering for epic visuals. No actual ambition nor reason to be doing what she's doing, completely out of character, an imbecilic psychopath just throwing a tantrum instead of having actual established ambitions and motives to ultimately accomplish something of worth on a grander scale. A shame. I did love she's actually voiced though, that was nice.
It's funny having predicted her ending too, but the way she accomplishes it is just so awfully executed. It screams to me; "Hey guys, we don't have the budget to make all this visually happen in Avernus, so lets instead have it happen in Baldur's Gate to save time and resources.". It's so cheap to cut corners like this and as is evident ends up destroying the character and the story.
