Another good one from my table. One of the party is a halfling sorcerer, who is rather disillusioned, but also one of the smartest of the bunch. In Shackled city, they are exploring a cave city, and he can see there is something in the water he just levitated over, back to the entrance where they have a guard they already beat but did not kill. The guard is tied up but barely conscious. The rest of the gang stands across the water, some distance away. He decides to solve the situation expediently. He gets the guard to his feet, pushes him into view of the others, shouts "NOOOO! YOU DON'T HAVE TO DO IT!!!", rushes toward the surprised guard, and pushes him off the shelf, down the painful slope of jagged stone, into the water, where he is promptly eaten by the thing in the water.
When the rest of the party reach him, they ask what happened. "It was horrible, the poor man... I couldn't stop him from jumping!!!" He then proceeded to roll a Bluff check and got 34. Everyone accepted it.
