This might be a hot take, but I actually like that Percy figured out Luke was the traitor at the last minute. There were A LOT of clues that would’ve been hard to ignore, and he ignored them for as long as he could. And it’s clear that even after accusing Luke, he’s still surprised and heartbroken at Luke’s confirmation of his suspicions. He was holding out hope, guys!!
Also, the Betrayal Scene flows better as an exchange of dialogue and a swordfight than it did, in the books, as a monologue and a scorpion sting. This also leaves a bigger impact on the viewers and characters because it’s more emotional.
The ages in this show!! I have made some jokes about this before, but it gets me - with aging Ciri up and bringing her closer to Jaskiers age when they meet I can not help but draw parallels. Like Geralt bonded way differently with both of them (which makes sense because Ciri has been his Child surprise since birth and Jaskier just randomly turned up one day and followed him like a puppy) but it's so funny to me. also I'm 100% sure Jaskier was horny as fuck from the beginning so there was a whole different vibe from the get go
