As it's also quite possible for hit to dies in the first encounter I really think certain NPC's need an essential/unkillable tag. Also, he needs a more cinematic introduction, Gale's so far is probably the best, although I don't like him that much as a character or where he appears, but -how- he is introduced is suitable.
Even Lae'Zel's introduction is a bit wierd, you can see her creeping on the ledge just waiting there for you. x) Shadowheart works because she's actually doing something. Astarion is just standing on the path in the open like a dumbass, I'd like if there was a small cut scene first where he jumps out at your from the bushes or something.
