Going with BG2 as well, I love spectator the beholder!
Spectator: "...oh, that reminds me. I promised that mad little sahuagain that I would make an attempt to scare off intruders..."
Spectator: "So... boo!"
Spectator: "And that's about as much effort as I'm willing to put into that. *sigh*"
Spectator: "Keep in mind that the drow who summoned me was mad. But, hey, who am I to judge. I suppose, I've been playing tic-tac-toe with a pair of imps for sixty years"
Spectator: "... sigh...."
Spectator: "Oh... in case you didn't hear an answer in that: No, you CAN'T look at what's in the chest. The drow specifically summoned me to guard *this* chest".
Spectator: "Hmmm. Well, he screamed "my chest" as I recall. A spear was being thrust through his own chest at the time, though, so he could have been referring to that".
Spectator: "Hmph. Is that it? Shoot, you'd have thought the whole future of drow race depended on it or something, the way that was drow was screaming".
Spectator: "*sigh* I suppose I have to resign myself now to guarding a completely empty chest for the next forty years. Yay".
Spectator: "Huh. You know... you're absolutely right. Not even drow mage would want me guard an empty chest. It's not even a *nice* chest".
Spectator: "There's no way that beholder council, bloated bladder-bags that they are, would hold me responsible for this contract! I.... I'm free! Yippee!".
Spectator: "What to do now? Hmm. Kill the imps... yeah. Those bastards deserve to die. But first, I'm gonna go eat something. You have *no* idea how hungry I am".
