It's definitely a thing that's been going through my head. Comparing notes about our respective kidnappings would seem like an obvious thing to do for anyone at all curious about what the mindflayers have been up to. Especially when it comes to folks like Lae'zel - where the heck was she when the squids got her? How did they get her? Was Gale in Waterdeep - did the squid raid go that far? How long has it been since everyone was kidnapped? It must have been a good amount of time since

Cazador has had time to recruit hunters to comb the countryside far and wide for Astarion.

I don't understand why no one's asking these questions.
